SUVA-TECH Trajecto is developed from the BATAK system which has been tested in real use conditions in various latitudes for almost 10 years ... Trajecto is a sophisticated, robust, sensitive and complete system. It is based on a Keysight TM brand low noise instrumentation class (500kHz / 16bit) acquisition card. It has 4 microphones based on the famous KNOWLES FG-23329 connected to low noise preamplifiers and 60dB of gain. One of the microphones is calibrated using a Bruel & Kjaer TM brand reference microphone. Ultrasonic transmitters built into the microphones are used to calibrate the system before use.
Using Trajecto is simple. All you have to do is to place the 4 microphones in a star configuration, to connect them to the central box, to sit in front of the computer and to start the Menuo program. Calibration is automatic. You just have to observe the trajectories of the bats that evolve above Trajecto.

Trajecto V1 EVO
TRAJECTO V1 EVO works identically to TRAJECTO V1. It uses new acquisition electronics developed by SUVA-TECH. Its performance is comparable to the TRAJECTO V1 for a lower cost.
Power is supplied by 2 x 9V batteries and the USB port.
TRAJECTO V2 is a system comparable to V1 and V EVO except that it can work without a computer. Data is stored on an SD card. Power is supplied by one 18650 LiPO battery and 2 x 9V batteries.

ANGULO is a compact antenna* which deploys very quickly making the use of the TRAJECTO system even easier. Due to its limited size it is mainly used for measuring bat flows to identify flight corridors and flight directions. However, it has a good 3D positioning accuracy for distances up to 10m** although it is able to identify calls up to a distance of about 30m** thanks to its sensitive microphones. ANGULO is therefore also a good tool for trajectory measurements in forest undergrowth.
ANGULO deploys like an umbrella and replaces the microphone set of the TRAJECTO system. On site, it can be set up very quickly, and then simply connected to the DR01 electronics of the TRAJECTO system.
