Veripos, suppliers of high-precision GNSS positioning to the world offshore industry, has introduced a new-generation configurable receiver designed to provide integrated mobile solutions for a wide range of offshore location and heading applications, the LD4 HDT.
Weighing less than 2kg, the compact IP55-rated unit can be configured to deliver a robust and accurate heading and any positioning solution provided by Veripos’s extensive range of satellite-derived services. Calculating differing positional solutions in addition to GNSS headings, the system can output both finished and raw data to external equipment and QC software for processing.
Using dual GNSS antennas to receive GPS and Glonass L1/L2 signals for subsequent computing of robust moving baseline vector/heading RTK fixed solutions, the LD4 HDT can typically provide either sub-metre or decimetre accuracies in addition to precision headings when receiving proprietary Veripos Apex and Ultra service corrections.
Upgradable for both future GNSS RTK operations and USB and Ethernet communications, typical system applications include back-up to mechanical gyro heading for hydrographic multibeam survey and geophysical vessels and construction barges. Others cover support for near-shore survey vessels requiring rapid mobilisation with low space requirements in addition to offshore construction emplacements involving remote monitoring via radio data telemetry.
