Correct way to use height and Delta U -Phase center

[Doppler_Uav]

Hi all,

I would need some help to understand the correct way to use RTKlib “positions” tab for Base. For example I have a known point with h=10.00m and the Antenna Reference Point 1.50m above that point.

Is this correct?

Antenna height= 11.50
Antenna Type = * - Auto from Rinex file (In my case I have a Trimble GPS as Base)
Delta U = 0.00

Or is the same if I use:

Antenna height= 10.00
Antenna Type = * - Auto from Rinex file (In my case I have a Trimble GPS as Base)
Delta U = 1.50

Or is another way to reach to the antenna phase center correctly?

In the case or the Reach I know that the phase center on the base of the Tallysman antenna, I only need to know the base.

Thanks!

You have to enter 1.50 only.

Hi @Doppler_Uav,

Have you configured the height in ReachView before log recording?

Hello @tatiana.andreeva, I am also new to all of this.
Does providing an antenna height under a Survey Project make a difference? Or how else to enter this before starting log recording?
Thank you!

Hi @FlatV,

I was not very attentive while I wrote the previous comment.

Yes, you’re right. The antenna heights specified in Survey Project isn’t recorded to a raw data log.
