A variety of RTK devices utilize a 0.96" or 1.3" high-contrast OLED display. See Configure From Display for information about how the navigation works on each model. While small, the display packs various situational data that can be helpful in the field. This section describes each possible display state.

RTK EVK - 1.3" OLED — Rover mode on the RTK EVK's 1.3" OLED display

Power On/Off

Press and hold the power button until the display illuminates to turn on the device. Similarly, press and hold the power button to turn off the device.

The device's firmware version is shown during the Power On display.

Force Power Off

In the event that a device becomes unresponsive, the device can be completely powered off by holding the power button for 10 seconds or more. The force-power-off method is hardware-based and will therefore work regardless of what firmware the device may be running.

If the power state of a device is not known (for example, because a display may be malfunctioning) the device can be connected to USB. If one or more COM ports enumerate, the device is on (shown above). If no COM ports are seen, the device is fully powered off.

Rover Fix

Upon power up the device will enter either Rover mode or Base mode. Above, the Rover mode is displayed.

MAC: The MAC address of the internal Bluetooth module. This is helpful knowledge when attempting to connect to the device from your phone. This will change to a Bluetooth symbol once connected.
HPA: Horizontal positional accuracy is an estimate of how accurate the current positional readings are. This number will decrease rapidly after the first power-up and settle around 0.3m depending on your antenna and view of the sky. When RTK fix is achieved this icon will change to a double circle and the HPA number will decrease even further to as low as 0.014m.
SIV: Satellites in view is the number of satellites used for the fix calculation. This symbol will blink before a location fix is generated and become solid when the device has a good location fix. SIV is a good indicator of how good of a view the antenna has. This number will vary but anything above 10 is adequate. We've seen as high as 31.
Model: This icon will change depending on the selected dynamic model: Portable (default) Pedestrian, Sea, Bike, Stationary, etc.
Log: This icon will remain animated while the log file is increasing. This is a good visual indication that you have an SD card inserted and RTK Facet can successfully record to it. There are three logging icons
- Standard (three lines) is shown when the standard 5 NMEA messages are being logged
- PPP (capital P) is shown when the standard 5 NMEA + RAWX and SFRBX messages are recorded. This is most often used for post process positioning (PPP) and 12 to 24-hour logs for fixed permanent bases.
- Custom (capital C) is shown when a custom set of messages are being recorded (not standard, and not PPP).
IP Address: On the RTK EVK 1.3" OLED, the full Ethernet or WiFi IP Address is shown at the bottom left of the display.

Once NTRIP is enabled on your phone or RTCM data is being streamed into the Radio port the device will gain an RTK Fix. You should see the HPA drop to 14mm with a double circle bulls-eye as shown above.

Base Survey-In

RTK Facet in Survey-In Mode — RTK device in Survey-In Mode

Pressing the Setup button will change the device to Base mode. If the device is configured for Survey-In base mode, a flag icon will be shown and the survey will begin. The mean standard deviation will be shown as well as the time elapsed. For most Survey-In setups, the survey will complete when both 60 seconds have elapsed and a mean of 5m or less is obtained.

Base Transmitting

Once the survey-in is complete the device enters RTCM Transmit mode. The number of RTCM transmissions is displayed. By default, this is one per second.

The Fixed Base mode is similar but uses a structure icon (shown above) to indicate a fixed base.

Base Transmitting NTRIP

If the NTRIP server is enabled the device will first attempt to connect over WiFi. The WiFi icon will blink until a WiFi connection is obtained. If the WiFi icon continually blinks be sure to check your SSID and PW for the local WiFi.

Once WiFi connects the device will attempt to connect to the NTRIP mount point. Once successful the display will show 'Casting' along with a solid WiFi icon. The number of successful RTCM transmissions will increase every second.

Note

During NTRIP transmission WiFi is turned on and Bluetooth is turned off. You should not need to know the location information of the base so Bluetooth should not be needed. If necessary, USB can be connected to the USB port to view detailed location and ZED-F9P configuration information.

Antenna Detection

On devices that support it, open circuit and short circuit detection is available on the GNSS antenna connection.

RTK EVK indicating antenna open circuit — RTK EVK with the GNSS antenna disconnected (open circuit)

RTK EVK indicating antenna short circuit — RTK EVK with a GNSS antenna cable fault (short circuit)

The RTK Facet mosaic hardware supports antenna detection, however, at the time of writing, the RTK Everywhere firmware does not. We plan to add this feature in the near future.

Corrections Source Icons

The RTK Everywhere Firmware will display an additional icon to show which corrections source is currently providing RTK corrections. If multiple corrections sources are active, the icon shows which source has priority. Please see Corrections Priorities for more information on how to prioritise the corrections sources.

The corrections source icon will appear on the bottom row of the OLED display, just left of the logging icon.

In the 1.3" screenshot below, RTK corrections are being delivered by PointPerfect over IP / MQTT:

In the 1.3" screenshot below, PPP services are enabled, and the PPP signal is detected over HAS E6:

In the 0.96" screenshot below, RTK corrections are being delivered by NTRIP (RTK2go / SNIP):

Each corrections source has a unique icon:
