This is the online product manual for the SparkPNT SXM-E; a high-performance, precision, all-band GNSS receiver. If this is your first time using the SXM-E, check out our Quick Start Guide for initial instructions on setting up the SXM-E as an RTK base station or NTRIP server. Again, thank you for purchasing our SparkPNT SXM-E!

Designed and manufactured in Boulder, Colorado, USA, the SparkPNT SXM-E is the perfect solution for your high-precision positioning and navigation needs. Based around the multi-constellation, multi-frequency mosaic-X5 module from Septentrio, this is our most advanced GNSS receiver to date. It supports signals from the GPS (USA), GLONASS (Russia), Beidou (China), Galileo (Europe), Navic (India), and QZSS (Japan) constellations with on-module support for future L-band signals. The mosaic-X5 module is a very sophisticated chip running a full internal web page server; where its position can be monitored and fully configured through that web page using a standard browser. It can be configured as a Real-Time Kinematic (RTK) Base Station to provide corrections to other RTK Rovers, or as an RTK Rover, where it can achieve a horizontal positioning accuracy of 6 millimeters (0.6cm + 0.5ppm). For research applications, the mosaic-X5 can deliver position updates at 100Hz (100 times per second), log raw GNSS data, and monitor/mitigate signal jamming or spoofing.


Under the hood, the SXM-E is powered by the mosaic-X5 GNSS module from Septentrio; and the Espressif ESP32-WROVER processor (16MB flash, 8MB PSRAM). The mosaic-X5 has USB-C connectivity (with Ethernet-over-USB), multiple UARTs, and supports full Ethernet connectivity. The only interface it doesn't offer is WiFi and that's why we've included the ESP32 with its own Ethernet connection. You can connect the mosaic-X5 directly to your Ethernet network - our product supports Power-over-Ethernet too. Or you can link the mosaic-X5 Ethernet port to the ESP32 Ethernet port and have the ESP32 provide WiFi connectivity. In that mode, the ESP32 becomes an Ethernet to WiFi Bridge, seamlessly passing WiFi traffic to and from the mosaic-X5 via Ethernet.
