On the selection of Alpha GPS, the GPS service starts here:
PPS Time: Indicates received time if GPS fix is working.
PPS Count: Indicates that the satellite is giving precise time pulses. PPS count initially is set to 0.
An increment of PPS count every second indicate that you are getting time pulses from the
satellite receiver.
A row in the Alpha GPS is highlighted in green if this satellite is used for the fix (Works only if
Alpha firmware version is 2.21 or greater) . When three or more rows are highlighted it indicates
that we have good GPS positioning. In this position, the PPS count shall start incrementing after
some time, since PPS count starts incrementing only when there is a 3D fix (5 satellites).
Latitude and Longitude: Provides the position of the Alpha.
PRN: Pseudorandom Noise code assignment.
SNR: Signal to noise ratio of the signal received from the satellite.
Elev and AZ: Elevation and Azimuth value suggests the angle at which the satellite is positioned.
Edit /Replace/Delete/Merge Alpha
The ‘
Merge alpha
’
option is only applicable to V2 alpha. Once the merge option is selected, you are
provided with a list of alphas to merge to the v2 alpha. On selection of the
‘Merge’ button
, all the
devices connected to the previous alpha are transferred to the new V2 alpha.
