What is SparkPNT?Product Overview
Designed and manufactured in Boulder, Colorado, USA, and utilizing the multi-band mosaic-X5 from Septentrio, the SparkPNT RTK Facet mosaic L-Band is the top-of-the-line receiver for high-precision geolocation and surveying needs. It’s incredibly easy for basic users to get up and running; for advanced users, the RTK Facet mosaic L-Band is a flexible and powerful tool. With just the press of a button, the RTK Facet mosaic L-Band is the fastest way to take centimeter-grade measurements. With built-in corrections, 6mm Real Time Kinematic fixes are less than a minute away. Connecting your phone to the RTK Facet mosaic L-Band over Bluetooth® lets your phone or tablet receive the NMEA output and work with most GIS software programs. This is exactly how $10,000 surveying devices have been operating for the past decade - we just made it faster, more precise, and much more economical.
The RTK Facet mosaic L-Band utilizes corrections from u-blox's PointPerfect service broadcast from a geosynchronous Inmarsat satellite. The only setup required is a WiFi SSID and password. Once entered, the device will provision itself and periodically (once a month) update the decryption keys necessary to use the PointPerfect service. This service requires an additional monthly subscription fee. Please see this page for more details.
Under the SparkPNT RTK Facet mosaic L-Band hood is an ESP32 WROOM connected to a mosaic-X5 GNSS multi-band receiver and various peripheral hardware (LiPo fuel gauge, microSD, etc.). Additionally, housed under the RTK Facet mosaic L-Band dome is a surveyor grade L1/L2/L5-Band antenna. This antenna combines elements designed to receive the GNSS signals (L1/L2/L5) alongside the 1.55GHz PointPerfect corrections. The RTK Facet mosaic L-Band is programmed in Arduino and can be tailored by you to fit whatever your needs may be.
This device can be used in a variety of modes:
- GNSS Positioning (~40cm accuracy) - also known as Rover
- GNSS Positioning with RTK L-Band (3cm to 6cm accuracy) - also known as Rover with L-Band RTK Fix
- GNSS Positioning with RTK (6mm accuracy) - also known as Rover with RTK Fix
- GNSS Base Station
- GNSS Base Station NTRIP Server
In addition to supplying position data, the RTK Facet mosaic L-Band can log NMEA and RINEX for post-processing, making it ideal for research and advanced positioning applications.
The RTK Facet mosaic L-Band is an open-source hardware product, meaning you can fully obtain, see, and modify the electrical and mechanical design files. This allows for easier maintenance and repair over time.
The SparkPNT RTK Facet mosaic L-Band kit includes everything you need: the enclosed device, thread adapter, charger, data cables, and carrying case.
