It combines the core electronics, antenna and logging hardware into a compact unit for geolocation, surveying and RTK projects.For everyday use, it pairs with a smartphone over Bluetooth. Your phone can supply correction data from an NTRIP service via the internet while receiving the high-accuracy NMEA position output from the RTK Facet.Inside the unit are an ESP32 WROOM, a u-blox ZED-F9P GNSS module, a LiPo fuel gauge and a microSD card slot for logging. The protective dome houses a surveyor-grade multi-band L1/L2 antenna with a precise Antenna Reference Point (ARP).The RTK Facet is fully open-source hardware and is programmed in Arduino, with access to the electrical and mechanical design files. It can log NMEA, RAWX and SFRBX data directly to microSD for post-processing and research.Specifications:Antenna Phase Center L1: 71.8mmAntenna Phase Center L2: 67.3mmAntenna Phase Center Average: 69.55mmFor a permanent base station, SparkFun recommends using an L1/L2/L5 surveying antenna with a protected reference station or a ZED-F9P breakout-based solution. **Product Type:** GNSS Surveyor ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDEbkCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--5e4754c27111e2fc0ffef66f0e1ec00d4c289f39/19984-SparkFun_RTK_Facet_Kit-02-1.png) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDErkCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--324876253a424847f93b6911b610ecb581f0d4be/19984-SparkFun_RTK_Facet_Kit-01_1.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDE7kCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--92db703468d531fd80b46ecf6f6631df2ef606c6/RTK_Facet_Photos-01a.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDFLkCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--937b332d4361b42bb3b77f9f234773254ec79ca4/17546-1_4in._to_5_8in._Adapter_for_5_8in._Thread-02_3.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDFbkCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--abc19eaec78be8b407beabf95d4e9486d5da40cf/17240-Breadboard_to_GHR-04V-S_Cable_-_150mm-01_1.jpeg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDFrkCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--04e204a49fe6b17cf95f497d1a33a6ed7aedaadc/17239-GHR-04V-S_to_GHR-06V-S_Cable_-_150mm-01_2.jpeg) - [Image 7](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDF7kCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--41aa781b7b6b4a10cb32b600173ff706b124978b/16893-USB_Wall_Charger_-_5V__2A-01.jpeg) - [Image 8](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDGLkCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--0dfdbe8e3452cf3b7f3d8344ccf523840062e280/15425-Reversible_USB_A_to_C_Cable_-_0.8m-01_5.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
