ISO 9001 / DUAL – USE / 100% EUROPEAN MANUFACTURING / SINCE 1992
━━━ THE PRODUCT
SATPROV3 is a professional dual-axis antenna tracker with absolute positioning. Unlike trackers that require a homing routine at start-up, it resolves its exact orientation immediately: the operator points the head roughly toward geographic north before powering on — and from that moment, as soon as GPS/telemetry data arrives, the system begins automatic, continuous tracking with no further calibrations.
Operationally this means zero start-up delay, no drift after a power cut, lower operator workload and lower risk of link loss at the critical moment. The system keeps the antenna pointed at the vehicle throughout the mission, preserving the command and video link at extended distances.
It is built for field deployment: a robust structure with quick-release arms, IP54 protection and thermal management for outdoor operation. Control is flexible — autonomous by telemetry, via network API, or hybrid — and it integrates with the XLRS ecosystem and with third-party radios and links.
━━━ WHY SATPROV3
EUROPEAN MANUFACTURER, FULL CONTROL
In-house design, manufacturing and support in Spain (EU). Not a re-assembly of third-party parts: full control of engineering, quality and integration.
PROVEN ABSOLUTE POSITIONING
No homing, no drift: lower operational risk, operational at once and stable tracking. Mature technology, refined in real operation.
PERFORMANCE / COST RATIO
Professional dual-axis performance with a competitive performance-to-cost ratio versus higher-priced systems.
FIELD-READY AND CUSTOMISABLE
A complete kit deployable in minutes and customisable to your project (finish, RF, firmware, IP rating) for orders and programmes.
DEPLOYED IN ACTIVE DEFENSE PROGRAMMES
Integrated with VTOL platforms by European defense integrators in real operational environments.
━━━ DEPLOYMENT & SET-UP
01 — ORIENT
Mount on the TRI276 tripod and aim roughly at geographic north. No tools: quick-release antenna arms.
02 — POSITION
On power-on, absolute positioning gives exact orientation at once. With GPS/telemetry data, the system knows where the vehicle is.
03 — AUTOMATIC POINTING
Begins autonomous, continuous tracking (azimuth/elevation), keeping the link pointed throughout the mission.
━━━ INTEGRATION & CONTROL
SERIAL TTL · TRANSPARENT
Third-party radio · no MAVLink · requires CTRCB + CURCB
Third-party radio without MAVLink connected via CTRCB adapter (TTL → RCBus). The GPS stream reaches the PC via CURCB (USB/COM). The PC application parses the incoming data and forwards the vehicle position to SATPROV3 over the network using the GPSOBJ command (TCP/UDP). Compatible with any radio with TTL serial output.
SERIAL TTL · MAVLINK
Third-party radio with MAVLink · requires CTRCB — XLRS WMX481V3 · direct, no adapter
SATPROV3 reads MAVLink GPS/telemetry natively and begins tracking automatically. Third-party radios connect via CTRCB adapter (TTL → RCBus); ground mapping software (Mission Planner, QGroundControl, UgCS) can connect simultaneously via CURCB (USB). The XLRS WMX481V3 connects directly via RCBus and Ethernet — no adapter required.
ETHERNET / API TCP-UDP
Any source connected to the SATPROV3 network
The data source connects to the SATPROV3 network. The PC application receives GPS data from any source and forwards the vehicle position to SATPROV3’s IP using the GPSOBJ command (TCP/UDP). Also supports MAVLink over network, NMEA, and direct azimuth/elevation axis commands. Works with custom GCS, mission software or supervision platforms.
In every mode, the operator points the head roughly toward geographic north before powering on — the system resolves absolute pointing from that reference, with no additional steps.
━━━ MANAGEMENT SOFTWARE
The SATPROV3 is managed from the XLRS_SATPRO software, PC application: real-time monitoring of azimuth/elevation position, tracking mode, GPS reception status, battery and system alarms. Manual overrides, API command console and firmware update from the same interface.
━━━ SEE IT IN ACTION
Two operation examples — recorded with the previous SATPROV2 generation. Tracking behaviour, interfaces and deployment process are equivalent to the current version.
