Position RMS |
Float |
|
The range residual RMS is the square root of the sum of the squares of the range residuals divided by the number of degrees of freedom in the solution. |
|
6 to 9 |
VCV xx |
Float |
|
VCVxx through VCVzz is the variance-covariance matrix. This contains the positional components of the inverted normal matrix of the position solution in a ECEF WGS-84 reference. |

Unit variance |
Float |
|
The unit variance of the position solution. |
|
34 to 35 |
Number of epochs |
Short |
|
Indicates the number of measurements used to calculate the position. Only “0” (zero) is expected since this antenna cannot be set with a STATIC constraint. |
