Permanent GPS network-based measurement practice in Israel
Forrai, Joseph
The development of the permanent GPS network in Israel has been initiated as an ultimate infrastructure for geodetic-geodynamic research. Following its establishment, the network which consists of 19 permanent stations, became a commonly used, multi-purpose measurement system, supporting research as well as geodetic control, cadastral, photogrammetric, engineering, topographic, GIS and mapping tasks. Current development aims at matching between new surveying regulations and high quality permanent GNSS applications and services. The permanent stations network, with its complementary services, makes the user possible to carry out many kinds of GNSS tasks using a single receiver. The coordinates computed directly refer to the valid datum and grid of the country. The use of a country-wide statutory geoid undulation model enables the user to determine orthometric heights by GNSS measurements, at a 25 ppm accuracy level, implementing a 3 dimensional geodesy practice.
