ProMark2 Antenna Values
Posted By fred youna on 9/18/2001 at 3:47 PM

These are the Value that was provided to us by Ashtech support.

0.0900 meter Antenna Radius

0.0516 meter Slant Height Measurement Point Offset

0.0693 meter L1 Phase Center Vertical Offset

double click on time window for the receiver and build a new Antenna with above data.

These antenna values (except for the radius) can be found in the Promark FAQ document

ftp://ftp.ashtech.com/Reference%20Manuals/PROMARK2/FAQ ProMark2.doc


Note that these are Mechanical phase center offsets, not Electrical. The Mechanical offsets will be very close to the Electrical phase center offsets values which the NGS is calculating for the Promark antenna at this time.

As long as antenna types are not mixed in the field (i.e. only Promark II antennas are used), and the same height measurement method is used on each Promark antenna, the differences in Mechanical Vs Electrical offsets will not be significant.
