piNAV-NG

Space-Friendly™ CubeSat GPS Receiver


Do you plan to Launch a Satellite into space and need a SatNav Equipment Onboard for a precise in-orbit Position, Velocity and Time? The piNAV-NG/FM (Flight Model) is a long-term optimized CubeSat GPS Receiver with a firmware based on many years of orbital operations heritage intended for modern satellites, CubeSats and majority of scientific/business/university projects, where the satellite development team requires a module with limited size and power budget.

 

DROP | Dead Reckoning Orbital Propagator

In case the antenna of the GPS receiver system is unable to pick up a proper signal quality, signal strength or locally (in-situ) the signal is jammed from (unfortunatelly) increasing amount of terrestrial sources powerfull enough to penetrate up to the LEO altitudes, making high areas of orbits without usable GPS signal, the Dead Reckoning Orbital Propagator (or DROP) algorithm serves as a mathematical solution implemented in the piNAV-NG firmware to overcome the GPS PVT/Fix dropouts with no need to uplink TLE or other orbital elements from ground, nor many hours of continual operations to collect the orbital data.

Orbital propagator alternatives such as SGP-4 would be considered much more accurate, however for its proper functionality it either requires the initial TLE uplink or much more Fix data to be collected over several orbits (several hours of continual GPS operations), which may not be an easily fulfilled requirement (satellite OBC restarts, power cycling, South Atlantic Anomaly or Single Event Effects induced bitflips or restarts, power savings with GPS receiver OFF, etc.). The onboard ADCS software however still can implement algorithms such as SGP-4 and work with valid GPS fixes only for maximum orbital determination precision, if needed.

Connect the proper GPS antenna via RF Coaxial cable and DC power from 2.7 to 3.3V and start to receive first signals from GPS constellation with piNAV-NG GPS Receiver in minutes!

piNAV-NG/EM (Engineering Model)

piNAV-NG

The Engineering Model (EM) with the same mechanical and electrical properties is available with software limitation to maximum velocity and altitude. Red Remove Before Flight Finish is applied to prevent interchange with the Flight Model unit. Connect the proper GPS antenna via RF Coaxial cable and DC power from 2.7 to 3.3V and start to receive first signals from GPS constellation with piNAV-NG GPS Receiver and start implement your Onboard Computer or Attitude Determination and Control Subsystem software!

Note: As the DROP (Dead Reckoning Orbital Propagator) requires an orbital velocity 7000-9000 m/s, it is not available in Engineering Model, thus also the Warm Start time is not defined.
