Dipper Field
Before you start
- A receiver connected and sending positions. If it won't connect, see the receiver won't connect.
- An RTK-capable receiver and an NTRIP account from a correction provider, or a receiver that gets corrections on its own.
Open Settings and tap Location source. Two things on the receiver screen tell you most of the story:
- Position type: Standard means no corrections are being used. RTK float means corrections arrive, but the receiver hasn't resolved its solution yet. RTK fixed is the goal.
- The line under RTK corrections: whether corrections are reaching the receiver.
Read the RTK corrections line
| It says | What to do |
|---|---|
| Receiving RTK corrections | Corrections are arriving. Skip to give it sky and time. |
| NTRIP is not set up | Tap NTRIP Settings and add the details from your provider. See get RTK corrections with NTRIP. |
| RTK corrections are disconnected | Tap Connect Corrections. To have it connect by itself, turn on Connect automatically in NTRIP Settings. |
| The username or password was not accepted | Check both with your provider. Passwords are case-sensitive. |
| A password is required | Enter the password in NTRIP Settings. |
| The mount point could not be found | Check the spelling, or use Choose from the caster's list. |
| The correction service rejected the connection | The account may be expired, already in use elsewhere, or not allowed on that mount point. Ask your provider. |
| The correction service returned an unsupported response | Check Caster address and Port, and whether Use encrypted connection should be on. |
| The correction service is unavailable | The phone can't reach the service. Check its mobile data or Wi-Fi. |
| Check the NTRIP settings | A setting is missing or invalid. Open NTRIP Settings and check each field. |
| Connected. Waiting for a position from the receiver to report to the service. | The service needs the receiver's position first. Take the receiver outside until it has one. |
| Connected, waiting for RTK correction data | Signed in, but nothing has arrived in the last 15 seconds. Check the mount point, and that your account covers it. |
| Reconnecting to correction service | The connection dropped. The app is trying again. Check the phone's signal. |
Time since last correction shows how old the latest correction is. It should keep dropping back to a second or two. If it keeps climbing, corrections have stopped.
When corrections can't reach the receiver
Dipper Field gets corrections over the phone's internet connection and passes them to the receiver. That needs a way to write to the receiver:
- This receiver has not offered a channel to write corrections to. Connect Corrections stays grayed out. The receiver's Bluetooth connection only sends positions. Check the receiver's settings for an RTCM input on Bluetooth, or let the receiver get its own corrections.
- This Bluetooth connection can read positions but cannot send RTK corrections to the receiver. Same cause, shown under the section.
- Port 10110 carries positions only, so the phone cannot send RTK corrections to the receiver over it. On Wi-Fi, connect to a port that accepts corrections, if the receiver has one, or let the receiver get its own corrections.
- Corrections dropped appears under Technical details when the link to the receiver couldn't keep up or dropped. Keep the phone close to the receiver.
When the receiver gets its own corrections
- Receiver fetches its own corrections; this device standing by. A Dipper receiver is getting corrections over its own Wi-Fi. If it still doesn't fix, check its correction settings under Device NTRIP Settings.
- The receiver is already being corrected by another source. Corrections from this device are paused. The receiver has corrections from elsewhere, such as its own modem or radio. Check that source in the receiver's own settings.
Give it sky and time
- Use a mount point near you. The farther the base station, the slower and less reliable the fix. Pick the nearest one your provider offers, or a network mount point that builds corrections for your position. Dipper Field sends the receiver's position to the service for that.
- Get a clear view of the sky. Trees, buildings, vehicles and your own body block satellites. Hold the pole straight up, away from walls.
- Wait. Going from RTK float to RTK fixed can take from a few seconds to a few minutes. Hold still while it settles.
- Check the satellites. Satellites used on the receiver screen shows how many satellites the receiver is using. A low count usually means the sky view is blocked.
