A Priori Standard Deviation Settings
| Item | Operation |
|---|---|
| Satellite | Set the satellite. If setting it ALL, the all parameters are set to the same value except for individual settings for satellites |
| Pos | Set the initial state standard deviation of satellite position (m). |
| Vel | Set the initial state standard deviation of satellite velocity (m/s) |
| Srp1,2,3,4-6 | Set the initial state standard deviation of the solar radiation pressure model parameters 1,2,3,4-6. The units depend upon the solar radiation pressure model. |
| Clk | Set the initial state standard deviation
of the satellite clock bias (m). If using White Noise process as the clock model, the standard deviation of the satellite clock bias is set as the value at every epoch. |
| dClk | Set the initial state standard deviation
of the satellite clock drift (m/s). Ignored unless the satellite clock model is Gauss-Marcov process. |
| Receiver | Set the receiver. If setting it ALL, the all parameters are set to the same value except for individual settings for receivers |
| Clk | Set the initial state standard deviation
of the receiver clock bias (m). If using White Noise process as the clock model, the standard deviation of the receiver clock bias is set as the value at every epoch. |

of the receiver clock drift (m/s). Ignored unless the receiver clock model is Gauss-Marcov process. |
| ZTD | Set the initial state standard deviation of the zenith total tropospheric delay (m). |
| dZTD | Set the initial state standard deviation
of the zenith total tropospheric delay drift
(m/h). Ignored unless the tropospheric delay model is Gauss-Marcov process. |
| Grad | Set the initial state standard deviation of the tropospheric gradient parameters (1st order and 2nd order terms) (m) |
| PosU,PosE,PosN | Set the initial state standard deviation of the Up, East and North components of the receiver position (m). |
| PBias | Set the initial state standard deviation of the carrier-phase bias (m). |
| Xp,Yp | Set the initial state standard deviation of the Earth Rotation Parameters Xp, Yp (rad). |
