Dpos vs rtk

[Del Maxfield]

My DPOS solution is off by several feet horizontal and about -90 feet vertical from my RTK on the same known point. The RTK is correct. Also, why am I getting lat and Lon instead of SPC in the Dpos report?

The vertical sounds like a geoid was not applied. Are you comparing the orthometric heights?

SPC are shown in meters about halfway down the page on the right.

Hi Adam,

The RTK Geoid was apparently O.K. so I thought the static would be too. Do I need to check that somewhere else for a static observation?

 

[Adam]

The report should show the ellipsoid height and the orthometric height. Did you send this to web dpos or send it thru jmt or jfield?

 

[Adam]

Also the several feet horizontal sounds like you have wgs instead of nad83.

Could be - I have a new more serious problem! Gust of Wind blew over T-2. Have a message that Gyroscope calibration is required!
How do I fix that?

I sent it thru jmt.

Del, just ignore the message. T2 doesn’t have a gyroscope. The message is seems to be for T3 receiver
