N2 Palm GNSS Receiver

The N2 Palm is a slim and lightweight GNSS RTK receiver featuring 1,590 channels and support for multiple global satellite constellations. Its compact 48 mm-thick body and approximately 670–720 g weight make it convenient for all-day field surveying. It supports Static, Fast Static, PPK and RTK surveying, while its integrated IMU provides tilt surveying up to 60° with approximately 2.5 cm accuracy, allowing surveyors to measure points without keeping the pole perfectly vertical. Key Features 1,590 GNSS channels Multi-constellation and multi-frequency GNSS tracking GPS, BeiDou, GLONASS, Galileo, QZSS, IRNSS and SBAS IMU tilt compensation up to 60° Tilt-survey accuracy: 2.5 cm Supports RTK, PPK, Static and Fast Static Integrated 4G LTE modem Integrated 410–470 MHz UHF radio UHF transmit power adjustable from 0.5 W / 1 W / 2 W UHF working range up to 15 km under ideal conditions Bluetooth 5.0 Dual Mode USB Type-C Up to 20+ hours operating time IP67 waterproof and dustproof Survives a 2 m drop onto concrete Android-compatible field data collection Supports CAD import and stakeout workflows RINEX and ComNav raw-data support Technical Specifications Specification SinoGNSS N2 Palm GNSS Channels 1,590 GPS L1C/A, L1C, L2P, L2C, L5 BeiDou (BDS) B1I, B2I, B3I, B1C, B2a, B2b GLONASS G1, G2, G3 Galileo E1, E5a, E5b, E6c, E5 AltBOC QZSS L1C/A, L2C, L5, L1C IRNSS L5 SBAS L1C/A RTK Initialization ≤10 seconds Signal Re-acquisition ≤1 second RTK Horizontal Accuracy 8 mm + 1 ppm RTK Vertical Accuracy 15 mm + 1 ppm Static/Fast Static Horizontal 2.5 mm + 0.5 ppm Static/Fast Static Vertical 5 mm + 0.5 ppm Long Observation Static Horizontal 3 mm + 0.1 ppm Long Observation Static Vertical 3.5 mm + 0.4 ppm DGPS Accuracy <0.4 m RMS SBAS Accuracy 1 m 3D RMS* Standalone Accuracy 1.5 m 3D RMS Tilt Survey Up to 60°, 2.5 cm accuracy Update Rate 1 / 2 / 5 / 10 Hz Internal Memory 8 GB; 16/32 GB options cited in documentation Bluetooth Bluetooth 5.0 Dual Mode UHF Frequency 410–470 MHz UHF Power 0.5 W / 1 W / 2 W adjustable UHF Range Up to 15 km in ideal conditions 4G LTE-FDD / LTE-TDD / WCDMA / GSM USB Type-C Pole Interface 5/8″ UNC female thread UHF Connector TNC Housing Magnesium-aluminum alloy Dimensions Ø149 ±1 mm × 48 ±1 mm Weight About 670 g Operating Temperature -30°C to +65°C Storage Temperature -40°C to +85°C Water/Dust Protection IP67 Drop Resistance 2 m onto concrete Charging Time <5 hours with QC2.0 Operating Time ≥20 hours Power Consumption RX ≤1.8 W; TX ≤3.6 W Main Applications The N2 Palm can be used for: Topographic surveying Land and cadastral surveying Construction surveying Road and infrastructure surveys Boundary surveys Stakeout GIS data collection Mapping RTK base/rover operations Static and PPK surveys Precision agriculture Marine surveying Machine-control applications Communication & Data The N2 supports RTCM 2.x/3.x and CMR/CMR+ correction formats and can output standard NMEA-0183 messages. ComNav Binary output can reach 20 Hz. It can also record GNSS observation data in RINEX and ComNav Raw Binary formats for post-processing. The associated software supports static and kinematic processing and can produce reports in formats including DXF, TXT and KML.
