Septentrio has released version 4.2 firmware for the AsteRx4, AsteRx-U and the newly launched AsteRx-m2. The 4.2 firmware brings higher output rates, low and constant latency, support for TerraStar-C and a built-in NTRIP caster. AsteRx-m2 UAS receiver. The 4.2 firmware targets machine control applications delivering higher output rates with consistent and low latency. Maximum output rates have increased on all platforms: up to 100 Hz for the AsteRx4 and AsteRx-m2 and 50 Hz for the AsteRx-U, with latencies better than 10 ms and 20 ms respectively. TerraStar-C is now supported, bringing precise point positioning (PPP) horizontal position precision to 4 cm. In addition, Septentrio algorithms deliver fast PPP re-convergence making PPP even more attractive for positioning in difficult environments. For the AsteRx4 and the AsteRx-U, the 4.2 firmware enhances ease-of-use by including a built-in NTRIP caster. Correction data from the receiver is available for up to 10 NTRIP clients (or rovers) over the internet. The caster supports up to three mount points and can also rebroadcast correction data from a remote NTRIP server. “For machine control and automation, Septentrio receivers have unique low-latency behaviour which is constant and independent of the update rate.” stated Francesca Clemente, Product Manager at Septentrio. She continued: “The 4.2 firmware demonstrates Septentrio’s commitment to advancing performance and functionality of its products.”
