GPS Status
[Survey] [GPS Status]
The GPS Status screen contains several index card-format screens providing real time status of the active receiver.
Receiver
The Receiver card displays information about the receiver mode and GPS solution quality.
Mode: Displays if the receiver is set to Off, Base, Rover, or Post Processing mode.
Memory: Displays the amount of memory remaining in the receiver’s internal storage card.
Battery: Displays the remaining battery charge in the receiver.
Satellites: Displays the number of satellites:
Used: By the receiver for the current GPS solution.
Locked: (Tracked) by the receiver.
[Reset Ambiguities]: Used to reinitialize the receiver’s RTK engine.
Solution: Displays the type and quality of solution. It will be one of the following values:
No Communication: Not receiving a response to commands.
No Data: Receiving an unknown or a bad response to commands.
No RTK Solution: Receiving a response, but the receiver is not computing a solution.
Autonomous: Receiving a stand-alone solution (accuracy is about 100 meters).
Code: The receiver is calculating a code differential solution (precision is about 1 to 10 meters).
Float: The receiver is calculating a carrier phase differential solution with float ambiguities (precision is
typically within 0.1 m to 0.5 m).
Fixed: The receiver is calculating a carrier phase differential solution with fixed ambiguities (precision is
typically within 15 mm).
H Precision: Displays the root mean squared (RMS) error of the horizontal solution reported by the receiver. It is
displayed in project units.
V Precision: Displays the RMS error of the vertical solution reported by the receiver. It is displayed in project units.
Note: This value is supplied by the receiver, and the software displays the receiver’s value without modification. Most
manufactures report this value at the 2 or 3 sigma level. However, since different manufacturers use different
statistical methodology, it is not necessarily valid to compare the RMS values between brands, or even between
models with different firmware.
