Description

Navigation processing for days 143 and 147 navigation data relating to the GHOST project

Change History (5)

Day 147

Using MORP (Morpeth) base station from IGS, this is the closest base station possible to the survey area and the only non corrupt data available.

PPP processing:

Lat 55 12 46.05085
Long -1 41 07.77766
Height 144.312

Navigation solution initially contains a separation error of ~20 cm, will continue trying to end of day to improve.

Edit: Mixed up ppp processing outputs

Day 113

Can't get a quality level of above 2, resulting in accuracy we can't be certain about. Trying PPP. High level of satellites

Day 147

Managed separation of 20cm with quality level 1, still trying to improve. This has a low level of satellites available.

Day 113
PPP processing resulted in 7 cm position accuracy on easting and northing, 10 cm on height. Separation is 20 cm for north and 5 cm for east, 80 cm for height.

Without basestation data this cannot be improved much, only basestation data available results in larger separation and worse accuracy.

Day 147

Estimated position accuracy is 5 cm on north and east, height is 7 cm. The separation cannot be improved beyond 20cm, PPP doesn't improve the data so will continue with Morpeth basestation.
