Overview

Built into a standard commercial backpack, the system includes an RFeye, environmental protection cover, the system includes an RFeye node, environmental protection cover, internally-mounted antennas, battery providing approximately 5 hours of useful life, power controller and charger, and high-capacity USB memory stick for local storage. Overall backpack weight is approximately 6 kg (13.2 lb).

Pre-programmable, flexible and easy to use
The system 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 allow mapping 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 Nodes for signal location purposes. In locations with poor GPS coverage, 'waypoint' based location logging may alternatively be used. Data is logged to a USB memory stick for easy transfer of data after each survey.

Built-in data processing and intelligence
The powerful Linux PC built into the RFeye Node allows for conditional data acquisition (including if-then-else constructs) and statistical analysis as the data is collected to maximise the usefulness of the survey. In addition, a netbook PC may be connected for monitoring signals received whilst the survey is underway.
