Honeywell Rate Sensor for Small Sats: MEMS-Based 3-Axis Rate Sensor

The demands of this market are low cost, size, weight and power. Using our heritage designs and adapting them to the specific Space market needs, Honeywell has created a market-leading rate sensor with a volume less than 82cm³, that weighs less than 145g, and nominally only requires 3 Watts of power. In-run bias stability is better than 1 deg/hr (1ơ).

The HG4934SRS follows a strict part selection and management plan that ensures the HG4934SRS achieves guaranteed TID and SEE radiation performance. The qualified design incorporates additional features that make it suited for use in Space such as sensor technology insensitive to helium exposure, mitigation of floating metal, and SEFI/SEU mitigation features
