Lengemann has made a handful of exciting and evolutionary improvements to our L-Net Network (TopNET GNSS Network), effective 3-16-09.
1. A multi base dual constellation solution (Network RTK) expressed NRTK has been implemented.
• Advantages are fixed solutions with centimeter accuracies in extremely rural areas where other RTN services struggle to acquire or maintain fixed positions
• Extremely rapid precise ambiguity fixes with redundant horizontal and vertical accuracy
• Guaranteed unmatched fixed position and production time
• We now have freedom to tie rovers who are operating on specific NGVD or other datum to a specified NRTKRS (Network RTK Reference Station)
2. The Entire Network reference frame has been updated to NAD 83 (NSRS 2007) & NAVD 88 datum.
• Horizontal accuracies to 0.04; Vertical accuracies to 0.07
• Works seamlessly within our L-Net network, FDOT, and CORS datum with proven better vertical consistencies
• All collection software checks live to NGS NAD 83 (NSRS2007) NAVD 88 adjusted monument within hundredths
3. NRTK-RS (Network RTK Reference Stations).
• All stations have the latest Topcon GNSS software engine.
• Support for all messaging formats including DGPS.
• Extremely clean static data with reliable 24/7 accessibility through our ftp site.
• Remote upgrade and Satellite analysis capabilities.
• GNSS antennas to accompany all stations.
4. Multiple RTN Applications supported
• Survey Rovers
• Machine Control
• Precision Agriculture
• GIS/Asset inventory
5. Technical Support
• A group of highly trained, friendly, accessible individuals for any application
• Group or field training in all applications
• 24/7 phone support
