These settings are detailed below.
Device:
The device used may be one of the following:
1. An internal or external radio receiver. Corrections will be
received through a UHF radio link.
2. An internal or external GSM modem. Corrections will be
received through either a network connection, of the
NTRIP or Direct IP type (TCP/IP or UDP/IP), or a phone-
like connection, of the Direct Dial type (modem operated
in CSD mode). To acquire corrections from a base
delivering its corrections in Direct Dial mode, you should
have been given the phone number so the rover can call
the base.
Internal vs. external modems:
– With ProMark 220, the internal modem is located in
the GNSS receiver/data collector and the external one
in a third-party device.
– With ProMark/ProFlex 800, the internal modem is
located in the GNSS receiver – not in the data
collector– and the external modem is located either in
the data collector running FAST Survey, or in a third-
party device.
– With EPOCH 50, the GSM modem can only be
external, either coming as a standalone device, or
being part of the data collector used to configure the
rover.
3. Another device connected to the data collector through a
cable connection. This may be any radio receiver not
supported directly by FAST Survey.
