Satellites

The Satellites window provides a list of the visible global navigation satellite systems connected to the rover’s GNSS receiver. It displays several parameters such as space vehicle name, name of signal, signal strength, and locktime.

SV	Name of GNSS satellite. Acronym stands for Space Vehicle.
Signal	Name of the GNSS carrier band.
RSSI	Measurement of the power present in a received radio signal. Measured in dBHz.
LockTime	The amount of time since the satellite last obtained signal and navigation data. Max amount of time is 131s. Lower value indicates the satellite is constantly losing signal.

There may be instances where the LockTime will constantly display lower values. One such case might be a LiDAR mapping system mounted to a rotorcraft. If the GNSS antenna is located beneath the rotor blades, there will be a degradation in LockTime due to the blades obstructing the GNSS antenna signal.
