The AsteRx-m from Septentrio has reached End of Life (EOL) and is being replaced by the AsteRx-m2.



The Septentrio AsteRx-m OEM low-power GLONASS/GPS dual-frequency RTK receiver is very compact. It is designed for hand-held units, mobile computing products and other devices where extreme accuracy, low power and smaller dimensions are required.
