Alaska notes - Back
{K. Skinner -- I personally know Alaska had a pair of Trimble 4700s several years ago. I don't know if they have purchased more gear since.}

Please note that the older equipment (4800's and 4700) are on a different radio frequency than the 5800/R6's.
California notes - Back
The only equipment we have is an RTK system we bought in 1992, so it is fairly outdated. We have 2 each of:
Trimble antenna 33429-00 L1/L2 microcentered with groundplane
Trimble receiver 4400
Trimble data collector TSC1
navigation: GPS

Magellan ProMark3 (1 unit in the Henderson office): 14 parallel channel system that works with GPS (L1)
Topcon GR-3 (two complete base and rover set-ups): 72 channel system that works with:
GPS (L1, L2 ,and L5 carrier, CA, L1 P, L2 P, and L2 C)
GLONASS (L1, L2, and L5 carrier, L1CA, L2CA, L1 P, and L2 P)
GALILEO (E2-L1-E1, E5, and E6)
When system becomes fully operational. 2 Base units, 2 Rover units, and 4 units total. 1 single phase mapping grade unit
Oregon notes - Back
We actually don't have any survey grade GPS equipment at this time at the Portland, OR field office. In the past two years we've borrowed from Washington and Utah, and on several occasions we've rented. We're hoping to acquire a Trimble R8 GNSS RTK system in the next year or two.
Utah notes - Back
The Utah WSC has one Trimble 5800 RTK setup (rover is a 5800, base has a 5700). I believe GLONASS is the navigation system. {The Trimble 5800 is not GNSS compatible -- K. Skinner}
Washington notes - Back
The Washington Water Science Center has two Trimble R8 receivers that are dual frequency and receive GLONASS signals. The two R8s have integral 0.5 watt radios transmitters, but they are only good for 1 mile or so. We do have a Trimble HPB 35 watt radio.
Also, we have a subscription service to a Real-time Network (RTN, sometimes called VRS) that provides real-time network corrections to our rovers via a cell phone. The network is only good for the state of Washington. No base station is needed and this type of operation has been the primary means of operation for us for the last few months
Maine notes - Back
We have a pair of Leica, System 1200, Type GX1220, GPS units. There is a simple firmware upgrade we can do to get the GLONASS, Galileo, and Compass satellites, but it would cost us significant money (I think it was about $5,000) so we have NOT upgraded our units.
Kentucky notes - Back
2 Trimble R8 units (base, rover) with glonass
1 TDL450 radio
1 Trimble TSC3 Controller
Indiana notes - Back
