Checklist

Work through a GNSS observation setup before you log — receiver, antenna, height method, control, settings and quality.

A field and study aid only — follow your organisation's procedures, project brief and QA requirements. Nothing here is stored.

Before you rely on this: First-pass guide only. Verify safety-critical or regulated work against the relevant standards, your project requirements and a qualified professional.

How to use this calculator

  1. Work down the receiver/antenna, point & control, settings and quality sections.
  2. Tick each item as you confirm it at the setup.
  3. Aim to clear the outstanding list before you start logging.

How it works

A GNSS observation is only as good as the setup behind it — a wrong antenna height, datum or logging setting can quietly ruin a session.

This sheet gathers the things to confirm before you log: receiver and antenna, the height and its method, point and control, the coordinate settings, and the satellite/PDOP quality.

Frequently asked questions

Why record the height method?

Slant and vertical heights are measured to different marks on the antenna. If you don't note which you used (and the antenna model), the processed height can be out by a fixed amount.

Is this official course material?

No. It is free study support mapped to surveying course levels — not official North Metropolitan TAFE content or advice. Always follow your lecturer and the official assessment brief, and check your own working.
