ZuluAlpha (Pty) Ltd operates a private 1,381 ha telescope and ground-station hosting facility near Sutherland in South Africa’s Northern Cape. We provide secure infrastructure for remotely operated telescopes, astrophotography systems, optical ground stations, satellite-tracking sensors and related space-domain-awareness instruments. Our first client system has been installed, with additional shared and private hosting infrastructure under development.

Sutherland offers some of the finest astronomical conditions in the Southern Hemisphere, with exceptionally dark Bortle 1 skies, low atmospheric moisture and approximately 270 usable imaging nights per year. ZuluAlpha is situated about 15 km from the Southern African Large Telescope and benefits from the same protected dark-sky environment that has made the region South Africa’s principal optical astronomy location. The ZuluAlpha site is approximately 1,570 metres above sea level.

ZuluAlpha is already operational and our first client system has been installed. The access road, secure telescope compound, solar-power system and core security infrastructure are complete. Construction of the shared roll-off-roof observatory is under way and remains on track for completion around September or October 2026. Dedicated fibre connectivity is also being installed. Private telescope enclosures and specialist ground-station infrastructure can be developed according to individual client requirements.

Long-term conditions around Sutherland indicate approximately 270 usable imaging nights per year. Not every usable night will necessarily be completely cloudless for the entire night, but the dry Karoo climate provides excellent year-round imaging opportunities. ZuluAlpha is beginning long-term on-site monitoring of sky brightness, weather and imaging conditions now that the first client system has been installed.

ZuluAlpha can accommodate a wide range of systems, including compact smart telescopes, advanced amateur and professional astrophotography rigs, research telescopes, optical ground stations, satellite-tracking cameras, space-domain-awareness systems and RF ground stations. Our shared roll-off-roof facility accommodates systems with swing diameters from 82 cm to 240 cm. Larger telescopes, private enclosures and antenna installations of up to approximately 12 metres can be accommodated through customised infrastructure. Please contact info@zulualpha.co.za with your system dimensions, weight, power consumption and connectivity requirements so that we can confirm compatibility.

Dedicated fibre connectivity is being installed, with the initial service operating at 100 Mbps. The connection can be upgraded to multi-gigabit capacity, including 10 Gbps or higher, according to client requirements. LTE connectivity provides backup and failover during upstream outages. Dedicated bandwidth, static IP addresses, client subnets, secure VLANs and other enterprise networking services are available by quotation.

ZuluAlpha’s secure telescope compound and primary security infrastructure are complete. Security includes: A fenced and access-controlled core compound Monitored CCTV coverage Controlled vehicle and personnel access On-site security presence Remote environmental and infrastructure monitoring Individually protected electrical circuits Automated weather protection for the shared observatory once commissioned Access to the site is restricted to authorised staff, contractors and clients visiting by prior arrangement.

Shipping instructions are provided once your reservation and equipment list have been confirmed. Equipment can be received through our Cape Town logistics arrangements or delivered directly to the Sutherland site by prior arrangement. Please coordinate all shipments with ZuluAlpha before dispatch so that we can plan receiving, storage, customs support and installation.

Clients normally supply the telescope, mount, cameras, control computer or controller, power supplies and all system-specific cables and accessories. ZuluAlpha provides the allocated pier or hosting position, facility power, network connectivity and core observatory infrastructure. We can also assist with sourcing equipment, adapter plates, computers, networking components and other installation requirements where agreed. A complete equipment list should be supplied before shipping so that we can confirm compatibility and identify any additional components required.

ZuluAlpha can coordinate with experienced freight and customs agents and assist with the documentation required to bring equipment into South Africa. Unless otherwise agreed, the client remains the importer of record and is responsible for import duties, VAT, customs charges and regulatory requirements. We can also discuss procurement through ZuluAlpha where a single locally issued invoice would be more convenient.

A conventional single-telescope system can normally be installed, balanced, polar-aligned, connected and tested within approximately two weeks of arrival, subject to equipment completeness, weather and technician availability. Complex systems, multi-instrument installations and equipment requiring custom fabrication may take longer. The proposed installation process and expected timeline will be agreed with the client beforehand.

The facility and its critical infrastructure are monitored continuously, and clients retain 24/7 remote access to their hosted equipment. This should not be confused with 24/7 human technical support.

Routine human support is provided during South African business hours. After-hours attendance, guaranteed response times and 24/7 operational support are available only through an appropriate commercial support agreement or service-level agreement.

Automated systems manage weather-related closures and critical protection of the shared observatory.

Standard hosting includes continuous monitoring of ZuluAlpha’s shared facility and routine maintenance of core infrastructure, including the observatory enclosure, power, network, security and environmental-monitoring systems.

Where reasonably practical, brief and occasional basic interventions are also included during South African business hours. These may include:

• A visual inspection of the hosted system
• A power cycle or reboot
• Checking whether the mount is safely positioned
• Reseating an accessible power, network or USB cable
• Confirming whether equipment appears physically secure

Standard maintenance does not include repeated interventions, fault diagnosis, software or firmware changes, equipment reconfiguration, major recabling, collimation, optical or sensor cleaning, custom fabrication or replacement parts.

Additional work is charged at the current rates:

• Basic remote hands: US$40 per hour
• Technical remote hands and diagnostics: US$80 per hour
• Engineering and advanced maintenance: quoted separately

Wherever reasonably possible, billable work is discussed and approved before it begins.

Comprehensive Imaging Maintenance is an optional plan for individual astrophotography systems hosted in ZuluAlpha’s shared observatory.

The plan includes:

• A monthly physical inspection of the telescope system
• A brief status report, including photographs where useful
• Checks of accessible cables, connectors, strain relief and obvious mechanical issues

• Proactive notification when a potential problem is identified
• Priority scheduling during South African business hours
• Up to 60 minutes of basic remote hands or 30 minutes of technical support per month

Unused support time does not roll over. Additional work is discussed with the client and charged at the applicable rate.

The plan costs US$89 per month or US$979 per year. It does not include guaranteed attendance or resolution times, after-hours support, equipment-uptime commitments or a service-level agreement. Commercial, institutional and mission-critical support is scoped and quoted separately.

Yes. Clients and prospective clients may visit ZuluAlpha by prior arrangement. Because the property is a private operational site, unscheduled public access cannot be accommodated. Please contact us in advance so that we can arrange access and ensure that an appropriate team member is available.

The ZuluAlpha site falls within the Sutherland Central Astronomy Advantage Area, which provides important protections for optical astronomy through controls on external lighting and activities that could increase dust or interfere with observing conditions. The site is outside the Karoo Central Astronomy Advantage Area applicable to the primary radio-astronomy protection zone.

The Sutherland site is outside the Karoo Central Astronomy Advantage Area. However, radio-frequency installations remain subject to applicable ICASA licensing, equipment approval and national telecommunications requirements. ZuluAlpha will review each installation’s proposed frequencies and operational requirements before it is accepted.

The principal requirements relate to limiting artificial light and controlling dust-generating activities that could affect optical astronomy. ZuluAlpha uses suitable external lighting, access controls and construction practices designed to comply with the protected astronomical environment. Project-specific requirements will be reviewed during planning.

Yes. ZuluAlpha has received final Environmental Authorisation for the development of its telescope and ground-station hosting facility near Sutherland. The environmental assessment and public-participation process was completed without material objections, and development is proceeding in accordance with the conditions of the authorisation and other applicable municipal and astronomy-protection requirements. Environmental Authorisation reference: NC/BA/26/NAM/KAR/SUT2/2025.

Licensing depends on the equipment, frequency band, service type and whether the system only receives or also transmits. Some receive-only equipment may be exempt, while other installations may require registration, type approval or spectrum authorisation. The client remains responsible for obtaining the required approvals. ZuluAlpha can assist with local coordination and recommend appropriate regulatory specialists.

Multiple frequency bands can be included within a coordinated application, but ICASA may assess and authorise each band or frequency assignment separately. Clients should provide the complete technical parameters for every proposed band. ZuluAlpha can assist with preparing site information and coordinating local regulatory support.

Requirements depend on the particular service and frequency band but may include: Applicant and company information Requested frequencies and bandwidth Antenna specifications Transmit power and EIRP Site coordinates Satellite or network details Equipment type-approval information Supporting technical diagrams Proof of payment of applicable fees Final requirements should be confirmed directly with ICASA or an appropriately qualified licensing specialist.

Unless specifically agreed otherwise, the client remains the licence applicant and licence holder. ZuluAlpha can supply site documentation, review technical information and coordinate assistance from South African regulatory specialists. Any arrangement under which ZuluAlpha applies for or holds a licence would require a separate written agreement.

Yes. Clients are responsible for arranging suitable insurance for their equipment, including transit, theft, accidental damage, electrical damage and environmental risks. ZuluAlpha maintains security and resilient infrastructure and exercises reasonable care when handling client equipment, but facility insurance does not automatically cover third-party equipment.

ZuluAlpha uses monitored power, battery storage, generator backup, surge protection and automated weather-safety systems to reduce operational risk. Clients nevertheless remain responsible for insuring their equipment. Liability, service interruptions and force-majeure events are governed by the applicable hosting agreement and website terms.

The shared roll-off-roof observatory will provide multiple hosting positions across the Compact, Small, Standard and Heavy categories. Capacity will be expanded in response to demand. The wider 1,381 ha property can also accommodate private telescope enclosures, research instruments and dedicated ground-station installations outside the shared facility.

Yes. ZuluAlpha can assist clients with selecting, sourcing, importing, assembling and commissioning complete remote telescope systems. Turnkey packages are quoted according to the client’s scientific or imaging goals, preferred equipment and hosting category. Clients may also ship existing equipment for installation at the site.

Telescope time and shared-instrument services are not currently part of our standard hosting offering. These services may be introduced as the facility and equipment base expand.
