Septentrio mosaic-H Heading Receivers
The Septentrio mosaic-H is a dual-antenna GNSS module that gives centimetre RTK position plus heading, pitch or roll in one 31 × 31 mm package. Eview builds it into the HB6 Pro and HB56H receivers, with 0.15° heading at 1 m baseline and RTK plus attitude output at up to 20 Hz.

Septentrio mosaic-H: frequently asked questions
It is a dual-antenna, dual-band GNSS module that outputs centimetre RTK position plus heading and pitch or roll. It tracks GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS, measures 31 × 31 × 4 mm and includes AIM+, RAIM+, IONO+, APME+ and LOCK+.
Heading accuracy depends on the distance between the two antennas. At a 1 m baseline it is 0.15° heading and 0.25° pitch or roll. At 5 m it improves to 0.03° heading and 0.05° pitch or roll.
The HB6 Pro, a 45 g dual-antenna receiver for drones, robots and USVs, and the HB56H, a flange-mount receiver with SD logging. Both output RTK and attitude at up to 20 Hz. Datasheets are available by email.
Both give 0.15° heading at 1 m. The mosaic-H is dual-band and supports position up to 50 Hz. The mosaic-G5 P3H is quad-band, smaller, lower power and lists Galileo OSNMA, with output up to 20 Hz. Septentrio does not list OSNMA for the mosaic-H.
The module outputs position at up to 50 Hz. In Eview’s HB6 Pro and HB56H, RTK position and attitude are output at up to 20 Hz. For 100 Hz with heading, use the HB10 or HB59, based on the AsteRx-m3 Pro+.
