The ER-102 is a four-system full- frequency external measurement antenna covering BDS, GPS, GLONASS and GALILEO, which can meet the requirement of measuring equipment of high accuracy and multi-system compatibility. The antenna phase center of this satellite navigation antenna id stable and high positioning accuracy.
1. The antenna part adopts the multi-feed point design scheme to achieve the overlap between phase center and geometer center, and the influence of antenna on the measurement error is minimized.
2. The antenna unit has high gain, the wave beam of directional diagram is widely, which can ensure the reception effect of low-elevation signal, and it can still be received normally in the case of more serious occlusion.
3. With anti multipath choke plate, it can effectively reduce the influence of multipath on measurement accuracy.
4. Waterproof, UV protection cover for the antenna can be long-term work in the field to provide protection.
