GNSS Heading Receiver Integrated with Tethered Aerostat Systems
Raven Aerostar, USA, a manufacturer of Lighter-Than-Air (LTA) platforms, has successfully integrated Septentrio’s AsteRx2eH, a single-board dual-antenna GPS/GLONASS heading receiver, into its tethered aerostat systems.
Raven Aerostar recently completed a maritime persistent surveillance solution demonstration, deploying a TIF-25K aerostat system aboard the High-Speed Vessel – SWIFT (HSV-2). Integrating the single-board AsteRx2eH dual-antenna receiver to replace a solution based on two separate GNSS receivers allowed Raven Aerostar to achieve a reliable and accurate heading solution while also decreasing deployment time and total cost of GNSS sensors.
The AsteRx2eH provides a compact and low power solution for precise positioning combined with accurate heading information, produced at a high output rate. The tracking of both GLONASS and GPS satellites allows the receiver to improve the availability and robustness of a solution in challenging environments. The AsteRx2eH is a globally acclaimed OEM solution with field-proven performance for land, marine and aerial applications. It is for example used on board helicopters and aerostats during stabilised flights hovering at low dynamics, where inertial sensors cannot easily provide a drift-free solution. Another application is delivering reliable heading information for driverless ground vehicles, even at very low speeds.
