Overview

The RFeye RoofBox comes configured with a choice of internally mounted broadband omnidirectional antenna or DF antenna array for AOA (angle of arrival) direction finding. The system is built into a standard commercial roof box and includes an RFeye node, antennas, power controller and back-up battery, and high-capacity USB memory stick for local storage.

The RFeye node may be pre-programmed with the required measurement profile (frequency range(s), measurement interval(s), resolution bandwidth(s), statistical processing required, etc.) prior to the start of the survey, allowing use by non-technical personnel where required. The built-in high accuracy GPS receiver is used to tag the data received to map data against location, and data is also time-stamped using the precision GPS-derived clock, allowing later TDOA (time difference of arrival) analysis against data from other RFeyes for signal location purposes. Data is normally logged to a USB memory stick for easy transfer of data after each survey, but may also be transmitted over the built-in GPRS/HSPA modem.

The powerful Linux PC built into the RFeye allows for conditional data acquisition (inc. if-then-else constructs) and statistical analysis as the data is collected to maximise the usefulness of the survey. In addition, an external PC may be connected for monitoring signals received whilst the survey is underway.
