The following table describes each field on the GPS Status screen for ATLAS correction type.
Field | Description |
Time | Current time |
Latitude | Vehicle’s current latitude position |
Longitude | Vehicle’s current longitude position |
Altitude | Vehicle’s current altitude |
Speed | Vehicle’s current speed |
Heading | Vehicle’s current heading in degrees |
Diff Age | Age of the corrections used in the DGPS calculation. For ATLAS, Diff Age is 10-18 seconds. |
Std Dev | (Standard deviation) Pseudo-estimate of the DGPS solution accuracy determined as the RMS value of the positional residual errors. Std Dev is valid only if 6 or more satellites are used in the solution calculation. Std Dev for Atlas: Basic is .5, Atlas BA is .3, and Atlas RC is .1. |
Status | Status of the GPS receiver to receive GPS differential corrections |
Correction Type | Type of differential correction being used. Correction Type is Atlas for all Atlas corrections. (To see current Atlas correction, see Subscriptions page) |
Station ID | ID of correction station |
Sats Used | Number of GPS satellites used to calculate the position |
Signals | GNSS signals being used |
Quality | Quality of GNSS signals |
SBAS PRN | Satellites used by SBAS |
BER | Bit error rate Relative strength of the correction satellites. In the case of WAAS, two numbers are shown separated by a hyphen. The number can be from 0 to 500, with 0 being the best and 500 being the worst. If BER > 20 verify the antenna has a clear view of the sky to properly find and track correction satellites. REBEL tracks multiple correction satellites, each satellite has a different BER, and the value in the BER field represents each value separated by a hyphen. For example, a value of 8-500 means REBEL has a very good signal on one satellite (BER=8) and is not receiving corrections from the other satellite (BER=500, the lowest reception value). Only one satellite must have a low BER value (less than 20) to provide differential corrections. |
Available Diff | Differential corrections the receiver is getting |
Excluded | Differential corrections the receiver is not using (excluded from the differential solution) |
Modes | Current operating modes that control various GPS tracking parameters |
Accuracy | RTK accuracy status value |
