Spectra Precision SP20 Portable GNSS

The Spectra SP20 handheld GNSS receiver offers innovative camera-enabled centimeter accurate logging in an everyday GIS and Survey tool.
Rugged, lightweight and versatile, the SP20 delivers high-end performance. Yet it’s an easy-to-use, time-saver tool that delivers the accuracy (meter to centimeter) you choose, that’s just right for the job.
With Android-based ease and versatility it’s the optimal tool for cadastral, construction, or topo surveys; a range of GIS jobs from data collection to inspection and maintenance; as well as for non-traditional geospatial professionals. The 5.3 ’’ screen neatly displays the new workflow using a camera to ensure 2D centimeter accuracy handheld and 3D centimeter accuracy with monopole setup. Integrated high precision GNSS

1 Accuracy and TTFF specifications may be affected by atmospheric conditions, signal multipath, satellite geometry and corrections availability and quality.
2 Performance values assume minimum of five satellites, following the procedures recommended in the product manual. High multipath areas, high PDOP values and periods of severe atmospheric conditions may degrade performance. Real time accuracies depend on SP20 accuracy option. PP accuracy obtained with ATOM files processed by SPSO.
3 SP20 cm used with Monopole accessory
4 Long baselines, long occupations, precise ephemeris used (5) Batteries can be stored up to +70°C.
6 Receiver convergence time varies based on GNSS constellation health, level of multipath, and proximity to obstructions such as large trees and buildings. Convergence can be improved in RAM eanbled regions.
