Hear from the Engineers at RATE: 

This GPS was designed and developed from August 2024 and launched in April 2025. Throughout the process, it underwent hundreds of test comparisons, including internal iterations and comparisons with competing products. Since everyone uses similar technical solutions, we can responsibly state that the performance of this GPS is on par with that of competing products. Under open-sky conditions without obstructions or interference, the time to first fix (TTFF) with 8 satellites is between 35 and 60 seconds (depending on the time and environment).

In addition, through multiple tests and verification with a spectrum analyzer, we have identified several factors that severely impact GPS performance (hopefully this helps everyone resolve signal issues):
1. The FC AT7456 (OSD overlay chip) generates harmonics that fall precisely within the GPS frequency band, significantly affecting satellite acquisition. It is recommended to keep the GPS antenna away from this chip or shield the flight controller.
2. Certain receivers, operating at specific refresh rates, can also produce interfering harmonics that degrade GPS satellite locking. Trying different receiver refresh rates or increasing the distance between the GPS and the receiver is advised.
3. Some video transmitters (VTX), due to RF circuit design issues, may emit spurious signals within the GPS band, causing interference. Keeping the GPS antenna away from the VTX is recommended.
