Determining upper air wind speed and direction using a compatible Warren-Knight balloon tracking theodolite has never been easier. This Pibal (Pilot Balloon) System includes a convenient handheld PDA computer (TDS Nomad) loaded with our latest version of PIBAL software. The PDA can be connected to the W-K theodolite for hands free data logging operation, or by using the PIBAL’s convenient manual entry feature.
The PIBAL calculates wind speed, direction, and balloon altitude and stores it conveniently in an easy-to-read log file, for future print out. The PIBAL system includes Warren Knight’s PIBAL software, a hand-held TDS Nomad PDA, and an 8 foot cable to connect the theodolite to a hand-held computer.
The Nomad PDA is designed for fast and accurate recording of azimuth 806 MHz processor, a long-life battery and integrated wireless capabilities like WWAN, GPS, 802.11g, and Bluetooth.Features a high-resolution, sunlight-visible VGA display that shows graphics and maps in crisp detail. The W-K Theodolite can also be attached to any Windows Operating Laptop System in place of the PDA System.
