A LATE Thursday submit about our latest RTK Surveying device that’s now accessible!
It ought to come as no shock that we love surveying instruments and we put numerous delight and energy into these we create right here at SparkFun Electronics. Due to all of you who use our RTK Surveyors, Expresses, or Sides, we have been proven a route and drive to create extra choices so that you can use. In the present day, we announce our latest product to hitch this line primarily based in your suggestions. Meet the SparkFun RTK Reference Station!
The SparkFun RTK Reference Station is the proper answer on your high-precision geolocation, surveying, and time reference wants. For fundamental customers, it’s extremely straightforward to arrange a set location NTRIP server, enabling RTK for rovers and whilst an NTP server for gear synchronization and an astoundingly correct time base.
RTK is brief for Actual Time Kinematics. A satellite tv for pc positioning receiver able to RTK takes within the regular indicators from the World Navigation Satellite tv for pc Methods (GNSS) together with a correction knowledge stream to realize improved positional accuracy. GNSS contains satellites from GPS (USA), GLONASS (Russia), Beidou (China), Galileo (Europe), plus particular extra satellites (e.g., SBAS and QZSS). On their very own, these indicators will ship ~30cm positional accuracy. An RTK receiver takes in an extra Actual Time Correction Message (RTCM) knowledge stream after which calculates the machine’s location with 1cm accuracy in real-time. RTK works finest when the correction knowledge is generated regionally; the ‘Rover’ receiver accuracy degrades as the gap (baseline) between it and the ‘Base’ producing the corrections will increase. With just some minutes of setup, the SparkFun Reference Station lets you generate that correction knowledge regionally and share it through Ethernet!
Underneath the hood, the Reference Station relies on the ESP32-WROOM processor and u-blox ZED-F9P multi-band GNSS module. It runs the identical open-source firmware as our different RTK merchandise. The Reference Station has 10/100 Mbps Ethernet connectivity and it may be powered by Energy-over-Ethernet (PoE). The microSD card is related through a 4-bit SDIO interface, offering an order of magnitude enchancment in learn and write velocity. Equally, the u-blox ZED-F9P GNSS module is related through a high-speed SPI interface, additionally offering an order of magnitude enchancment within the GNSS knowledge switch velocity. Wish to log RAWX and SFRBX from all constellations at 20Hz? With this product, you’ll be able to! We additionally included an ATECC608A crypto co-processor if you wish to write your individual firmware and use the Reference Station for crypto mining/house climate station purposes or to safe/authenticate your GNSS knowledge.
This machine can be utilized in a number of modes, together with:
- GNSS Base Station with NTRIP – RTCM corrections are despatched to a Caster over Ethernet
- Community Time Protocol (NTP) Server – offering high-accuracy timing knowledge to different machines through an Ethernet community
These two modes are those most customers will need to use, however you by no means stop to amaze us with the number of methods you utilize our merchandise. Do you have to need to, the Reference Station may also be used as:
- GNSS Positioning Receiver (~30cm accuracy) – also referred to as ‘Rover’
- GNSS Positioning with RTK (1.4cm accuracy) – also referred to as ‘Rover with RTK Repair’ – utilizing NTRIP RTCM correction knowledge over Ethernet or out of your cellphone through Bluetooth
- GNSS NMEA/UBX TCP Consumer – sending NMEA and/or UBX navigation knowledge to a distant server utilizing TCP over Ethernet
The RTK Reference Station comes with all the pieces it is advisable to rise up and operating. Our equipment contains:
- Cased Reference Station
- L1/L2/L5 GNSS Surveying Antenna
- Bolstered RG58 TNC-SMA Cable
- SMA WiFi / Bluetooth Antenna
- 32GB microSD Card
- USB-C Energy Provide (wall charger)
- USB-C Cable
- Ethernet Cable
What else would possibly you want? Effectively, it depends upon the place you’re going to set up and use your Reference Station. One apparent place can be up in your roof the place your antenna may have the perfect view of the sky. Through which case you will have some {hardware} to assist mount the antenna:
Lastly, please see the Hookup Information for extra particulars on which configurations we have tried and examined.
And that is it for at this time! Be sure to examine again tomorrow the place Nathan stops by to showcase the equipment in slightly deeper element. You may think about the video that we have put collectively as details about the RTK Reference Station straight from the horse’s mouth. Thanks for stopping by and we’re extraordinarily excited to see what you make with this new surveyor. We’ll see you tomorrow!
