Ultra Low Power GNSS modules designed by Kolmostar

Our Prduct

JEDI-100 is Kolmostar’s ultra-low-power GNSS module. Built on the superior performance of the Kolmo JEDI engine, it integrates SAW filter, stand-alone LNA, and TCXO. Designed for IOT applications, especially for integration with LPWAN, such as LoRaWAN™/NBIoT, JEDI-100 not only achieves industry record low power consumption, but also enables AGPS through LoRaWAN™/NBIoT. JEDI-100 reduces the energy to get one position fix in cold start to 0.0038mAh, 70x lower than traditional GNSS sensors. With JEDI-100, one 200mAh battery can last for three years if position is updated every 30 minutes.

JEDI-100 consumes less than 8mA when it computes one position every second. JEDI-100’s performance is further improved when it works together with our Kolmo-AGNSS services.

Traditional AGPS services have to download an ephemeris files that is as big as a few KB to the GPS module. However, mobile devices in LPWA network usually can not afford to download such a big file.

Our Kolmo-AGNSS services use customized ephemeris file as small as only 100 Byte and have the ability to shorten the time-to-first-fix (TTFF) from more than 30 seconds to 2 seconds. The accuracy of the positioning results remain the same. After being powered up, JEDI-100 only requires less than 0.004mAh to compute one position, which greatly improve user experiences and extend battery life of mobile devices. One 200mAh battery can last for three years if position is updated every 30 minutes.
