Guides
The precision-GPS industry buries simple ideas under acronyms. These guides explain what the technology actually does, where it works, what it costs across the market, and what accuracy really means — claims separated from measured results, with every number carrying the conditions it was measured under.
Multi-band, multi-constellation GNSS, Bluetooth to your phone, signed over-the-air updates with rollback, and an open protocol — the capabilities, plainly.
The two ways to get precision GNSS, explained by their trade-offs — convergence time, coverage, cost — and what we measured with each on the same vehicle.
What a correction stream actually does, how it reaches the receiver through your phone at about 1 kbps, and the measured numbers behind 'fixed in seconds'.
Where the RTK subscription works as of August 2026 — the regions covered, the gaps stated as clearly as the coverage, and what to do if you are outside them.
Phone GPS is limited by its antenna, its single-frequency chip, and the uncorrected atmosphere — not by a setting you can change. What actually improves it, and what does not.
RTK turns metre-level satellite positioning into centimeter-level positioning by measuring the errors instead of guessing them. What it is, what it needs, and what it will not fix.
The real price of centimeter GPS across the market — dealer bundles, base-and-rover kits, bare boards, and phone-connected receivers — including the year-two costs nobody quotes.
What each level of guidance accuracy actually costs you in overlap and skip, why pass-to-pass and year-to-year are different numbers, and which jobs need centimeters.
How an external RTK receiver connects to an iPhone, the difference between system-wide location and app-level integration, and what to check before you buy.
