* Easy to integrate GPS L1 Antenna * Patch antenna * Antenna Cap * LNA * Test panel * Small dimensions * Low power consumption * No special knowledge for integration

—- ====== pNav2 Design Requirements ====== ==== Original pNav Design Requirements ==== * The CubeSat navigation receiver should be as simple as possible. * It should integrate all necessary parts for navigation in the LEO Orbit * It should be compatible with a 1U CubeSat platform, ie, power consumption should be a fraction of the power budget of 1U satellite. The receiver should be small and light. * The applied signal and measurement processing algorithms should be simple and very robust ==== + New Design Requirements ==== * Rapid Cold Start and satellite reaqusition * Continuous positioning of a rotating (unstabilized) 1U CubeSat * Easy integration into the satellite
