Comparison of u-blox ZED-F9P and ZED-X20P
If you need high-precision GNSS, you’ve probably come across the u-blox ZED-F9P and ZED-X20P modules. Both offer centimeter-level accuracy, but they offer different features for different users. Here’s a quick breakdown:
ZED-F9P: a reliable dual-band GNSS module
The F9P is a dual-band (L1/L2) RTK GNSS receiver that revolutionized the RTK market in 2018. It is known for its fast RTK fix times, high accuracy and low cost. If you are budget driven it works very well in open environments where you have good satellite visibility:
- Good for drones, robotics, and industrial automation
- RTK support with fast fix times
- Works best in open areas with minimal signal blockage
- Update rate limited to 10 positions every second
ZED-X20P: a next-gen all-band GNSS module
The X20 is a more powerful F9P. An advanced all-band (L1/L2/L5 and L6) GNSS receiver that offers better signal availability and improved accuracy in tough conditions. It can use more signals per satellite, making it more reliable in cities, forests, or near large structures. It also supports global PPP services, meaning you can get accurate positioning even without RTK corrections.
- Better performance in urban areas and challenging environments
- All-band for higher accuracy and position reliability
- Supports PPP for positioning without a local base station
- Update rate up to 25 positions every second
If you’re working in open areas and need a fast, affordable RTK fix, F9P is a solid choice. If you need better performance in cities, near obstacles, or in remote areas, X20 is worth considering. A detailed comparison table follows to help you decide which module best fits your needs.
