This article reviews some of the recent results analyzing the feasibility of carrier-phase based positioning with smartphone data and highlights limitations largely arising due to the poor antenna quality. It shows how they might be overcome by antenna calibration or coupling to the phone’s inertial sensors. The goal is to perform a successful RTK positioning with the smartphone-quality data.
Discussions about spectrum allocation, familiar to GNSS designers and manufacturers on Earth, are now taking place regarding the lunar environment. ITU Radio Regulations constitute an international treaty governing all radio frequency activities. This article shows that GNSS operators in this region must transmit signals in the GNSS S-band rather than in GNSS L-bands.
A new method for multipath rejection employs a multicorrelator-based GNSS receiver with an extended Kalman Filter (EKF) as an iterative solver, replacing the conventional delay locked loop (DLL) code tracking. The technique significantly reduces the positioning error and has low complexity. It can therefore be implemented in a real-time processing environment.
