2.2.9.2. GPS antenna advice for Ellipse-D

The Ellipse-D embeds a survey grade GNSS receiver that supports L1/L2 GPS, GLONASS, Beidou and Gallileo
signals. For best performance and robustness, please follow these recommendations.

Parameter

Specifications

Remark, conditions

Antenna connector

SMA female

IP-68 when connected

In order to enable proper heading measurements, L1/L2 GPS antennas are required, and tracking other
constellations is recommended for optimal performance.

SBG Systems has selected some high quality GPS antennas for different applications. Please refer to the
section 5.5 GNSS antennas to get more details on available antennas.

Note: As a rule of thumb, true heading and/or RTK measurements require higher quality GPS

antennas to achieve the stated accuracy.
