FAQ: Smart Antennas series

What is RTK GNSS and what accuracy can I expect?

What is the difference between L1/L2/L5 and All-Band RTK receivers?

L1/L2/L5 receivers track three specific GPS frequency bands and offer excellent RTK performance at a lower cost and weight — ideal for most UAV and IoT use cases. All-Band receivers additionally track GLONASS, Galileo, BeiDou, and NavIC across all their bands, which means faster RTK initialization, better reliability in difficult environments like urban canyons or under tree cover, and stronger multipath rejection. In this collection, 9 out of 12 products are All-Band.

Do I need a base station to use an RTK receiver?

You need a correction source, but not necessarily your own base station. You can use an NTRIP service over the internet, set up your own base with a second RTK module, or use the mosaic-G5 LoRa boards which broadcast RTK corrections over radio up to several kilometers with no internet required.

What is a Smart Antenna vs a plain RTK receiver board?

A Smart Antenna combines the GNSS chipset and a high-quality multiband antenna in one ultralight housing. You get positioning output over UART or USB without sourcing a separate antenna. A receiver board gives you more flexibility for custom enclosures and OEM designs, but you supply your own antenna. The smart antennas in this collection weigh as little as 20–40 g, which is why they're popular for drones.

What is the mosaic-G5 P3H Dual Smart Antenna and when do I need it?

It uses two antennas separated by a fixed baseline to compute the heading (yaw) of a vehicle with ±0.1–0.3° accuracy, without needing a magnetometer. This matters when motors or power cables create magnetic interference, or when you need accurate heading at standstill. Typical applications are autonomous ground robots, precision agriculture tractors, marine vessels, and ADAS testing. ELT0777 is the complete ready-to-use system; ELT0762 is the bare module for custom integration.

What do the mosaic-G5 LoRa boards offer that others don't?

They combine the Septentrio mosaic-G5 RTK receiver with an onboard LoRa radio so a base and rover can exchange RTCM corrections wirelessly over several kilometers with no internet or SIM card needed. This is ideal for field surveying, remote agriculture, or construction sites without cellular coverage. ELT0763 adds USB-C and JST connectors for easier prototyping; ELT0760 is the clean PCB version for OEM use.

What is the Budget M10 RTK board and for whom is it suitable?

The ELT0601 starts at €74.99 and is the most affordable entry in the collection. It's based on the u-blox M10 platform and is aimed at developers and hobbyists who need a USB-C ready GNSS module without a large budget. It won't deliver centimeter-level RTK accuracy, but it's a solid choice for prototyping, IoT asset tracking, and projects where decimeter-level accuracy is sufficient.

Are these modules compatible with ArduPilot, PX4, or ROS?

Yes. All modules output standard NMEA 0183 and RTCM 3.x over UART or USB, so they work with ArduPilot and PX4 out of the box — just connect to any GPS port and configure Moving Base for dual-antenna heading. ROS and ROS2 are supported via the nmea_navsat_driver or a custom driver. Septentrio mosaic-based modules also support native SBF and GSOF binary output for tighter integration.

What connectors and interfaces do the smart antennas use?

Smart Antennas (ELT0757, ELT0737, ELT0237, ELT0761) use UART with JST-GH or bare pads plus USB-C, powered at 3.3–5V. InCase boards (ELT0601, ELT0461) use USB-C for power and data with an SMA port for the external antenna. LoRa boards (ELT0760, ELT0763) have USB-C, JST, and SMA for both GNSS and LoRa antennas. Dual heading modules (ELT0762, ELT0777) use dual UART plus USB-C. All products ship with datasheets and pinout diagrams.

What GNSS constellations and signals do these receivers support?

It depends on the chipset. Unicore UM980 and Septentrio mosaic-G5 and mosaic-X5 cover GPS, GLONASS, Galileo, BeiDou, and NavIC across all available bands. The u-blox ZED-F9P covers GPS L1/L2, GLONASS L1/L2, Galileo E1/E5b, and BeiDou B1/B2. The ZED-X20P adds L5 and expands constellation support. Choosing an All-Band receiver generally means more tracked satellites at any given location, which translates to faster RTK fix and better availability in obstructed environments.
