# 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. |

{% hint style="info" %}
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.
