Level staff reading: staff leaning? Your reading is too high.

A staff that isn't plumb always reads high, because the horizontal line of sight cuts it further up the face. Two fixes, shown with the ComNav DS3-SN32X automatic level.

1. Centre the staff bubble so the staff is plumb, and check the bubble is in adjustment now and then.
2. No bubble? Rock the staff slowly through plumb. Watch the centre hair fall, then rise, and book the lowest reading.

Example: plumb reads 1.437; leaning 4 degrees reads 1.441, so 4 mm too high. Diagrams are illustrative and readings are examples.

Total station backsight check: 10 mm out after setup?

The backsight sets the orientation for every shot. Here are 3 fast checks, shown with the ComNav TS-C300 total station.

1. Prism constant: make sure the entered constant matches your prism. Enter 0 for a -30 mm prism and every distance reads 30 mm long.
2. Target height (HT): a wrong HT puts every height out by the difference. Hold the pole plumb, prism facing the instrument.
3. Check shot to a third control point, one you didn't set up on or backsight to. Observe face left and face right and take the mean.

Screens and diagrams are illustrative; distances and tolerances are examples. Always use your job spec.

GNSS RTK base on an unknown point? Every rover point moves with it.

3 fast checks for your rtk gps base and rover setup with the ComNav Jupiter receiver and ComNav R80 controller in ComNav Survey Master:
1. Auto base or Fix position: Device, then Base, then Start mode.
2. Antenna height and a matching rover: same protocol and frequency, wait for Fixed, pole plumb.
3. Prove it: Site Calibration or Grid Shift, then a check shot on a known point you did not use.

In the UK, a UHF base radio needs an Ofcom licence; without one, use the Vector RTK network over NTRIP.

ComNav Jupiter and ComNav R80: Contact Vector RTK for pricing. Free RTK licence included with the rover.

gnss rtk: splitting a farm into rental parcels?

This Short follows a topographical survey of a Norfolk farm with a ComNav T30 on the Vector RTK VRS network. Hedges, ditches and gates coded, spot heights for drainage, parcel areas in hectares and acres, and corners staked out. No base to set up, just Float to Fixed.

The parcels shown are survey plots for letting, not legal boundaries. Areas on screen are example values.

gnss rtk: far from your base and stuck on Float?

A VRS network keeps your baseline short wherever you work. Reference stations stream to the caster, your rover sends its GGA position, and the caster builds a virtual base right beside you, then streams RTCM corrections back over NTRIP. The result is consistent accuracy, faster and more reliable fixes, and no base to set up.

Works with ComNav Jupiter, ComNav Mars Pro and ComNav R80 rovers. Contact Vector RTK for pricing.

GNSS RTK residuals too high? Find the bad pair in your site calibration

One bad pair spoils the lot. 3 fast checks in ComNav Survey Master:

1. Read the residuals: Project, then Site Calibration, add pairs, then Compute. The Survey Master user guide asks for H.Resid of 0.015 m or less and V.Resid of 0.02 m or less.
2. Find the bad pair: wrong point paired, wrong antenna height, pole not plumb, Float instead of Fixed, or control in a line or all to one side.
3. Fix it, then prove it: re-measure that pair or set its Use to No, compute again, then check on a point you didn't use.

GNSS RTK fixed but 40 mm out? 3 fast checks on your RTK fix

Fixed means the ambiguities are resolved, but multipath can still give the wrong whole number, and H.RMS and V.RMS are only the receiver's own estimates.

1. Check shot on a known point: key it in, set the antenna height, keep the pole plumb, measure it Fixed and compare with the known coordinates.
2. Compare with your job tolerance. If it's outside, stop and find the cause.
3. Re-initialise with Reset RTK, wait for Fixed again and re-measure. Both results should agree within tolerance.

GNSS RTK innovation funding: where to look in the UK

Developing a new way to use GNSS or RTK? Innovation and regional funding may help with a wider project.

Where to look: Innovate UK competitions on the Innovation Funding Service (each competition has its own eligibility, and some are open to collaborations only), the UKRI funding finder, Scottish Enterprise funding and grants if you are in Scotland, and your local council, as the UK Shared Prosperity Fund has been delivered through local authorities.

Funding is competitive and never certain: you may be eligible, so check the scheme rules. General information only, not funding advice.

Example kit shown: ComNav T30 GNSS receiver. Contact Vector RTK for pricing.

Talk to Vector RTK about your kit and RTK plans.

GNSS RTK mapping for heritage and community archaeology projects

Planning a community archaeology or heritage project? Centimetre-accurate RTK GNSS mapping can make your site records more useful.

National Lottery Heritage Grants of £10,000 to £250,000 are open to not-for-profit organisations, private owners of a heritage asset and partnerships, with no deadline. Survey kit or survey work may be one part of a wider heritage project, so ask the funder which costs it can cover. The Society of Antiquaries of London also runs grant programmes.

Funding may help but is never certain: you may be eligible, so check the scheme rules. General information only, not funding advice.

Example kit shown: ComNav T30 GNSS receiver. Contact Vector RTK for pricing.
