Eleven ways to get a precise position: pick the one that matches your job, not the other way around.
PRECISE's GNSS Receivers & Accessories line covers the full chain of a positioning workflow: rover receivers that capture points in the field, base stations that generate corrections, antennas that feed clean signal into fixed installations, a radio that extends your correction link, and a field controller that carries and records your data. Every product runs on the same MATRIX positioning core; the difference between them is which part of the job they're built to handle.

Which One Do I Need
Physically Unreachable Points
Your points are sometimes physically unreachable (across a ditch, up a slope, behind a fence, inside a pit, near a power line).
X9
The flagship receiver with a built-in 120 m laser for contact-free measurement, image measurement within 15 m, dual-camera AR stakeout, and tilt survey — the most ways to reach a point without walking a pole to it.
Everyday Visual Stakeout
Your work is standard survey and stakeout, and you want a more intuitive way to find the stakeout target — see the point, not just the numbers.
X9 Lite
Bottom-camera visual stakeout with real-scene guidance for the final approach, plus base/rover flexibility and on-receiver control in one receiver.
Laser Measurement on a Budget
You need contact-free measurement of unreachable points (up to 70 m) without stepping up to the flagship.
X7
RTK, 70 m laser, tilt, and AR stakeout in one receiver — the established all-in-one for points a normal pole can't reach.
Everyday Survey & Tilt Stakeout
Your work is standard survey and stakeout, with tilt measurement at obstructed points a daily occurrence, but you don't need laser, AR, or a camera view.
X7 Lite
The same calibration-free ±60° tilt IMU as X7, plus a full connectivity set (4G, Wi-Fi, built-in UHF), at a lower cost without cutting corners on RTK reliability or durability.
Canopy & Mixed-Coverage Areas
You work under tree canopy, in mixed-coverage areas, or need AR to speed up finding stakeout points.
X
1,808 channels and 21 frequency points built for faster, more consistent fixes in obstructed sky conditions, plus worldwide PPP correction as a fallback.
Is X9 Lite Just a Cheaper X9?
Whether X9 Lite is a stripped-down, budget version of X9.
No — Different Focus
X9 Lite is built for the everyday survey and stakeout work that makes up most field days — visual stakeout, base/rover flexibility, on-receiver control — not a stripped-down X9. Choose X9 only when reaching physically inaccessible points (120 m laser, image measurement) is a recurring part of your work.
No CORS or Cellular Coverage
You need RTK coverage for field survey work where CORS or cellular doesn't reach.
BASE2
A portable field base station you bring to a job site, set up in minutes, broadcasting RTK corrections up to 30 km in open terrain.
Continuous Structural Monitoring
You need to continuously watch a structure (bridge, dam) for deformation over time.
C
A permanently installed monitoring receiver, mounted once and left running for months or years, streaming raw position data over Ethernet. Not a rover-facing base station.
Limited Installation Space
Installation space, weight, or mounting conditions are limited.
AN2
Compact (Φ180 × 180 mm, < 2.5 kg) anti-multipath antenna, phase center error < 2 mm.
Extreme Multipath, No Space Limit
High-grade reference stations and extreme multipath environments (bridges, dams, ports, marine sites) where installation space isn't the limiting factor.
AN4
Full 3D choke-ring design (Φ379 × 312 mm, 9.3 kg bare), phase center error ±1 mm, six-constellation plus L-Band coverage.
Built-In Radio Range Falls Short
Your base station's built-in radio (5W on BASE2, 2W on X or X7 Lite) can't reach across a large site, long linear project, or hilly/obstructed terrain.
PL2
A high-power external UHF radio with selectable 10 W / 30 W output to extend the correction link between base and rover.
Consumer Devices Aren't Holding Up
Your crew uses a consumer phone or tablet to control an RTK receiver or total station, and battery life, ruggedness, or reliable data entry is a recurring problem.
PC3
A rugged handheld Android field controller (5.45" touchscreen + physical keyboard, 9000 mAh battery, IP68) that pairs with X7, X7 Lite, X, or a PRECISE total station.
FAQ
Common Questions
Start with X9 Lite unless you regularly need to measure points a pole can't physically reach. X9 Lite covers standard RTK survey, visual stakeout with bottom-camera guidance, tilt measurement at obstructed points, and base/rover flexibility in one receiver. Move up to X9 only if long-range laser measurement (120 m) or image measurement of inaccessible points, or X if AR stakeout guidance and tree-canopy performance, are recurring needs on your projects.
Not necessarily. BASE2 exists for situations where CORS or cellular network coverage isn't reliable: rural sites, mountainous terrain, or projects where you need an independent, project-controlled correction source. If your CORS/NTRIP service reliably covers your project area, your rover receiver (X9, X9 Lite, X7, X7 Lite, or X) can connect to it directly without a local base station.
C is built for permanent, continuous installation on a structure. It streams raw position data to a monitoring system 24/7 for months or years. X7 is a field rover, carried on a pole and used for daily survey and stakeout work. They're not interchangeable: C is not designed for rover fieldwork, and X7 is not designed for unattended long-term structural monitoring.
No. X9, X9 Lite, X7, X7 Lite, and X have integrated antennas built into the receiver body. AN2 and AN4 are standalone antennas for fixed installations, primarily paired with C for structural monitoring, or with other reference station receivers where a dedicated high-precision antenna is required.
If your rovers are staying in range and holding a fixed solution, you don't need PL2. Add it when the built-in radio on your base station (5W on BASE2, 2W on X or X7 Lite) can't reach across the site, typically on large open sites, long linear corridors, or terrain with line-of-sight obstructions.
