“Correction source” parameter
Source from which the receiver obtains its correction data to increase the position accuracy.
The list of selectable correction sources depends on the licenses that are available on the NAV-900.
The display of the parameters to be configured changes depending on the selected correction source.
- ▪
- “Autonomous”
- No correction data is used to improve the accuracy. The position is only determined based on the satellite positions.
- ▪
- “SBAS”
- These are free satellite-based correction services, e.g. EGNOS, WAAS, MSAS and GAGAN.
- ▪
- “RangePoint RTX”
- Is a satellite-based correction service that is available virtually worldwide for path to path accuracy of 15 cm. A local base station or modem is not required.
- ▪
- “CenterPoint RTX Satellite”
- Is a satellite-based correction service that is available virtually worldwide for accuracies of up to 2.5 cm. A local base station or modem is not required.
- ▪
- “CenterPoint RTX Satellite Fast”
- Initialisation time of less than 1 minute. CenterPoint RTX Fast is available is selected regions and does not require a local base station or a modem.
- ▪
- “CenterPoint VRS”
- Refers to the correction method in which the RTK corrections are sent to the GNSS receiver per mobile Internet through a network consisting of base stations and servers. An external GSM modem is required.
- Select this correction source if you are using the NAV-900 with the GX450 modem.
- ▪
- “CenterPoint RTK”
- Refers to the correction method in which the RTK correction data is sent to the GNSS receiver by a local base station through a radio connection. It requires either an external radio modem or an external GSM modem.
