Overview
Kalmix Market Insights is a GNSS and RTK selection series covering RTK module versus receiver trade-offs, RTK GPS for outdoor robotics, and price-tier comparisons to help engineering teams choose hardware for robotics, AGV, and field automation.
How to read RTK accuracy tests by comparing datasheet specs, Fixed Rate, RMS, CDF, and scenario statistics before choosing a receiver.
RTK GPS can improve field mapping, but acreage, boundaries, datum, antenna setup, and export metadata decide whether the map still lines up later.
Phone-based RTK is a packaging decision: move the antenna and positioning engine outside the handset while the phone keeps apps, maps, and network.
Field-trial repeatability depends on correction source, datum records, iOS or Android app support, drone GCP reuse, and a clean RTK point archive.
SparkFun RTK is excellent for lab prototypes, but field wiring, enclosures, and support can make a packaged receiver the cleaner path.
ArduSimple simpleRTK boards are strong for RTK evaluation, while integrated receivers reduce enclosure, antenna, wiring, and support work in the field.
RTK module vs RTK receiver is a build-or-buy decision: who owns RF, power, enclosure, firmware, validation, and the cost of taking hardware into the field.
RTK for robotics gives outdoor machines a global reference. This guide covers sensor fusion, correction health, trust states, and field failure handling.
