Page 19: Appendix B - Cellular Antennas And Amplifiers
TECHNICAL REFERENCE MANUAL APPENDIX B - CELLULAR ANTENNAS AND AMPLIFIERS Cellular Connection One of the main problems with a VRS Network RTK solution is the need to maintain a reliable and constant cellular connection. When considering an RTK VRS problem, make sure to FIRST check for cellular connection. - Page 20 TECHNICAL REFERENCE MANUAL PPN High Gain Antenna We carry a very good 5dBi high gain antenna that works very well at receiving even sparse cellular signal. It is a Magnet Mount Antenna with a 14" Mast, 3" Magnet Base and Enclosed Coils with FME Female Connector.

Page 21: Appendix C - Glossary
TECHNICAL REFERENCE MANUAL APPENDIX C – GLOSSARY APN (Access Point Name) Identifies an IP packet data network, that a wireless mobile data user communicate with. An APN may also be used to define the type of service and the priority of that service. For example a group of users may setup a special APN for their RTK data that insures high priority and low latency vs. - Page 22 TECHNICAL REFERENCE MANUAL GNSS Global Navigation Satellite System - Generic term for systems such as GPS and Galileo. GPRS General Packet Radio Service - a non-voice data service for the mobile telephone network. Global Positioning System - US owned positioning satellite constellation. Gives 10-20 m accuracy as standard.
- Page 23 TECHNICAL REFERENCE MANUAL NTRIPServer In practice, the NTRIPServer is software running on a conventional PC that sends correction data from a GNSS receiver (COM-port) to a third installation (from NTRIPSource to NTRIPCaster). As an example NTRIP could be used within a virtual reference network where the protocol is able to transport RTCM data.
