The range of chl a concentrations from the water samples at the reference station
For the differential positioning of the buoy, a coastal reference station
is necessary as close as possible to the calibration area.
MicroZ CGRS is one of the most powerful permanent GPS reference station
available, designed for continuous use and effective collection of high-quality data.
The software also supports radio and cellular communication links; Trimble's new extended RTK (eRTKTM) technology for single-base, multibase and virtual reference station
(VRSTM) networks; and upcoming DGPS services around the world.
Prior to the arrival of the refurbished shelters, the concrete foundations for the two reference station
towers are installed along with cable runs to bring the cabling from the equipment hut to the reference station
Allnav GmbH, a distributor for Trimble in Switzerland, is to install a permanent GPS reference station
at Zurich International Airport using a Trimble TT450S radio link to provide position accuracy.
This type of system locates positions using the carrier wave of the GPS signal and a signal emanating from a reference station
very close to tractor operations, on the corner of the test site.
The HVSR and HVNR techniques do not need a reference station
and they are based on the computation of the horizontal-to-vertical spectral ratio of the components of motion recorded at only one seismic station.
The reference station
separation is usually restricted to less than 100 km to allow for quick and reliable ambiguity resolution.
Global Positioning System (GPS) technology solutions provider Trimble is to supply the New Zealand Institute of Geological and Nuclear Sciences Limited (GNS) with 40 Trimble NetRS reference station
Trimble has supplied Global Positioning System (GPS) reference stations
and Virtual Reference Station
(VRS) software to LE34 Tele A/S to establish GPSnet.
