Base configuration
After logging in to the reference station, user can choose from the following settings:
MODE
Reference station can operate in two modes:
- GOTRACK-RTK.COM mode
In this mode reference station does not need fixed and public IP address since all correction data is sent to the gotrack-rtk.com server which is NTRIP caster and rovers (GOtrack computers) connect to the gotrack-rtk.com server not directly to the reference station.
- INDIVIDUAL mode
In this mode reference station requires FIXED and public IP address since rovers (GOtrack computers) connect directly to the station. Base station becomes NTRIP caster itself.

Mountpoint
Settings available only when reference station works in INDIVIDUAL mode. When in GOTRACK-RTK.COM mode settings are available at your gotrack account after loggin in.
Moutpoint is the name of the RTK fix access point that will be visible when selecting correction source on a GOtrack or other RTK device.
The name of the access point can be anything but it is suggested to use simple and concise names.
In the Mountpoint menu, the user can also set the port number on which corrections for client devices will be available, i.e. Rovers. The default port number is 2101. You can change the port number freely. After making the change, remember to make changes to the port forwarding on the router in the local network.

Users
Settings available only when reference station works in INDIVIDUAL mode. When in GOTRACK-RTK.COM mode settings are available at your gotrack account after loggin in.
The user of the reference station can enter any number of usernames and associated passwords.
For each user, you can also define the number of devices – clients that can be connected to the reference station at the same time. If a negative number is inserted, there is no limit. The number of all connections to the reference station is limited by the plan purchased from the distributor. The free plan includes up to two users connecting at the same time. The name of the purchased plan and the possible number of parallel connections with the reference station are displayed in the header of the device configuration page.

Base position
The position of the base station is the basic setting of the reference station, having a critical impact on the proper operation of clients – rovers. Only the precise positioning of the reference station will ensure precise and reliable operation of the receivers.
ATTENTION. The reference station must be installed where the entire sky is visible. The mounting method must ensure position stability, i.e. the housing cannot change its position in windy weather.
The reference station has 3 modes of operation.
1. Survey-in
2. Survey in and Fix
3. Fixed mode
In the survey-in and survey-in and fix modes, the user defines two parameters that affect the way the device learns its position. They are time and precision. In order for the reference station to start generating RTCM corrections, both conditions must be met, i.e. the set learning time must elapse and the position precision must be achieved during this time. Otherwise, the device will not start generating RTCM corrections.
The default learning time is 6 hours.
Default precision – 5cm
The longer the learning time, the better the position of the reference station will be calculated. It is recommended that this process be given due attention. The imprecise position of the reference station will affect the precision of operation of the receivers – rovers.
Survey-in
In survey-in mode, the reference station will learn its position when powered up. This is a deprecated mode because if the learning time is too short, the position of the device may be imprecise.
Survey-in and fix
In this mode, the reference station, after learning its position, saves it to its memory and the next time after turning on the power, the device will start in the fixed-mode mode with the saved position.

Fixed – mode
In the fixed – mode, in the configuration menu, enter the geographic coordinates of the location of the reference station and its altitude above sea level. Coordinates are given in the WGS84 standard.

RTCM
The reference station generates RTK corrections in RTCM 3.3 format. The user can choose any set of RTCM messages that are necessary for the receiver – rover in order to achieve high precision of measurement.
Depending on the type of receiver the user has at his disposal, it is possible to define the appropriate RTCM messages to be sent to the receiver.
The user may select each message separately or may select a set of messages of a given standard, eg MSM4 or MSM7. You can also select RTCM messages only for specific satellite constellations: GPS, GLONASS, GALILEO.
Some receivers require RTCM 1008 messages to function properly.

Base login
In the base login menu, the user can change the password or phone number.

WiFi
The reference station can work in two WiFi modes. Access Point mode and Client mode. In the Access point mode, it is possible to connect directly to the device via the WiFi interface in order to configure the device. In client mode, the reference station can connect to an existing wireless network. In the client mode, it is possible to log into the reference station’s configuration page only via the local network (direct connection mode is not possible). The reference station can also be connected to the Internet via WiFi. For the proper operation of the device, you should properly configure router in the local area network. Remember about redirecting the appropriate ports to the local address of reference station if in INDIVIDUAL mode. The device’s default ports are listed in the Network Requirements section.
Restoring the default settings of the WiFi interface and returning to the Access point mode is done by pressing and holding the button on the device housing for at least 10 seconds.
WiFi network configuration.
Network
In the NETWORK tab, the user can configure each of the network interfaces separately. If DHCP for a given interface is on, then the device gets an IP address in the local network automatically from the DHCP server. If DHCP is turned off, the IP address of the reference station in the local network is set by the user manually in this menu.
When configuring network settings, you should match them to the existing local network by setting a local IP address in the same class and indicating the appropriate default gateway.
Configuring network interfaces: WiFi and Ethernet.
GSM
The reference station is equipped with a GSM LTE module. This module is used for communication with the Internet and for sending SMS messages that can inform about the device status.
In the GSM menu, you can enable or disable data transmission or sending messages using the ON / OFF switches.
In order to properly configure the LTE modem’s connection to the Internet, the correct APN must be entered. Please contact your mobile network provider for the correct configuration settings.
ATTENTION!!! To obtain a fixed IP address, some mobile network providers provide a non-standard APN.
