McMurdo Sea Ice Runway (NZIR) survey #1
0127 data on
0205 moving
0245 still (no postcal)
GPS receivers:
UAVJ: vehicle
02QR and 3VYU: ground station (Thiel gravity hut)
3VLZ: Rac tent (on sea ice airport)
We placed an Ashtech choke-ring antenna on its magnetic mount atop an NSF van. We measured
antenna heights from the top of the antenna's radome to the ice surface, which was hard and
quite level. Measured antenna heights were:
pre-survey:
251.1 cm
251.2 cm
251.1 cm
251.1 cm
250.9 cm
250.8 cm
250.7 cm
250.7 cm
AVG: 250.95 cm

251.4 cm
250.9 cm
250.6 cm
250.7 cm
250.0 cm
250.6 cm
250.5 cm
AVG: 250.67 cm
OVERALL AVG: 250.82 cm ICE SURFACE TO TOP OF RADOME
Computed: 241.49 cm ICE SURFACE TO LC PHASE CENTER

We placed an Ashtech choke-ring antenna on its magnetic mount atop an NSF van. We measured
antenna heights from the top of the antenna's radome to the ice surface, which was hard and
quite level. Measured antenna heights were:
no pre-survey measurements (we were pressed for time)
post-survey:

252.3 cm right side
253.6 cm right side
252.3 cm left side

252.0 cm left side
OVERALL AVG: 252.43 cm ICE SURFACE TO TOP OF RADOME
Computed: 243.10 cm ICE SURFACE TO LC PHASE CENTER
