Abstract:	Indoor positioning with GNSS encounters several limitations. One is the power of the signal that is too weak indoors. The Assisted-GNSS (A-GNSS) and High sensitivity GNSS (HS-GNSS) are answers to the weak signal problem. They allow decreasing the detection level of the satellite signal down to -150 or -160 dBm which makes signals measurable in “light indoor” environments ("light indoor" corresponds to environments where the signal is not totally absent like the top floor of a building or nearby the windows). However the attenuation of walls and roof can easily overtake 30 dB in very common cases: A-GNSS and HS-GNSS are then inefficient.
