GPS receivers of Sierra Wireless AirPrime modules can be connected to a passive antenna (which should be physically located very close to the unit) or a remote active antenna containing an LNA, which will both improve SNR and compensate for any cable/insertion losses.
This application note describes the use of the integrated GPS active antenna powering function when available, and how to design an external powering circuit where required.
