The stats bar and its badges

Every Survey and Grade screen has a white bar across the top: live numbers on the left, small square badges on the right. The badges are buttons. Learn the colours and you can tell at a glance whether the GPS, the connection and the elevation calibration are good.

Before you start

• You are on a Survey or Grade screen. The bar is at the very top of the screen, above the map.
• Reading this page takes about five minutes. Tapping a badge only opens a window; it changes nothing by itself.

The numbers, by screen

Each number has its name in small grey letters under it. On the Grade screen:

On the Survey screen:

• Survey: Distance, Points, Start Elev, Current Elev, Drop, A→B Grade (%). See Survey screen.
• Grade (Slope-IQ, Forming): Current (blade elevation), Target (this pass), Design (final design; only shown when a nudge or Auto-Nudge makes it differ), Nudge (green up, red down).
• Leveling: Current, Target, Nudge.
• Manual Grade: a grade chip (for example 0.30% ↓, with Seg 2/3 when there are several segments), Current, Dist from 0+00, Target, Nudge.
• Excavation: Current, Target, Cut/Fill, and Dist and Grade when grading to a grade or design.

Elevations show -- until there is a fix. Units follow the UNITS card in Settings.

With Auto Nudge switched off and no nudge, Design drops out because it equals Target:

The badges

The square badges at the right-hand end of the bar. Their order differs a little between screens:

• Survey screen: GPS, BM, Wi-Fi, wrench.
• Grade screen: GPS, the Auto Nudge switch (or CH / BERM in Terracing, before the switch), Wi-Fi, BM, wrench.

GPS badge

The first, widest badge: a target icon, the fix label in the fix colour, the number of satellites and a small ⓘ.

• RTK, green: RTK Fixed. The only fix endorsed for survey and grading.
• FLOAT, amber: RTK Float. Wait for the fix.
• PPP, amber: a precise-point service some receivers report. Not RTK; not endorsed.
• DGPS, yellow: differential GPS, about a metre. Not good enough to grade. (A John Deere StarFire SF-RTK reports DGPS on a real RTK fix; see DGPS on an RTK receiver.)
• GPS, orange: standalone GPS, no corrections.
• NO GPS, red: no position.
• SIM or N/A, grey: the receiver says its position is simulated, estimated or typed in. N/A in red: the receiver sent a fix code the app can't use.

The app's built-in simulator steps through NO GPS, GPS and FLOAT in its first few seconds, then holds RTK. With a Bluetooth receiver a small Bluetooth icon sits next to the target icon. When no new position has arrived for the GPS Delay Timeout (5 s), the whole badge dims: the numbers are frozen. Why the fix changes: RTK explained.

To see the details: tap the GPS badge. A window called GPS Info opens with the source, status, satellites, HDOP, position and elevation, and, where the source sends them, PDOP, correction age and the Wi-Fi signal. Tap the X at its top right to close it. Every row explained: The GPS Info window.

Wi-Fi badge

• Green Wi-Fi icon: connected (control module, DIG™ module, Reach, Bluetooth receiver or simulator).
• Grey crossed-out icon: not connected. Tapping it says Tap a workflow card on the Home screen to connect.

To see what you're connected to: tap the green Wi-Fi badge. A small window opens, titled with what you're connected to (for example Ditch Assist DIG, Emlid Reach …, Bluetooth GPS or Simulator), with Device, Fix, Satellites, HDOP and, when known, Firmware. Tap Close to shut it. Disconnect ends the connection.

BM badge

The small square badge with the letters BM. It shows whether an elevation calibration is applied. Tap it to open the Calibrate Elevation window; the status line at the top of that window tells you exactly which state you're in.

Because the colour alone can't tell you, open the badge and read the status line:

The badge is never green. Grey is fine when you survey and grade in one session on one base setup. When you need to calibrate, and how: Benchmarks and calibration.

Auto Nudge switch

On the Grade screen in Ditching, Simple Grading, Terracing and Land Forming: the words Auto Nudge with a switch after them. It turns Auto-Nudge on or off for this job: on, the sidebar shows the AUTO-NUDGE pass buttons; off, Nudge Up / Nudge Down. It doesn't change the default in Settings. See Nudge and Auto-Nudge.

To change it: tap the switch. Green with the white knob on the right is on; white with the black knob on the left is off.

CH / BERM

Terracing only: a small tag after the GPS badge, CH (green) or BERM (blue), naming the terrace target you're grading. Switch it with the Channel / Berm buttons in the sidebar.

Wrench

The last badge, with a wrench (spanner) icon. Tap it to open Settings. While auto grading, it first opens a window called Stop Auto-Grading?: tap Stop & Navigate to stop the blade and open Settings, or Stay to keep grading. Your progress is saved either way.

On other screens

The Field Survey, Levee and LiDAR & Mapping screens have their own top bars (point and benchmark counts, contour counts, steering). The GPS badge works the same everywhere.
