WTAPRS: Tough Wind Turbines ... for a Tough World

APRS World's WT10 micro wind turbine is the premiere wind generator for extreme wind enviroments. We have spent years developing and testing the WT10 in downright brutal locations and applications. Regular 150+ MPH winds, ice, and lightning. Every component of the WT10 has been repeatedly revised to make it as tough as possible and work in the most demanding enviroments. Simply put, there isn't a tougher micro wind turbine on the market.

Besides the WT10 wind turbine, we manufacture turbine control panels, output cables, dump loads, tower components, specialized installation tools, and even highly innovative mounting structures for ISO shipping containers. With our years of experience in data acquisiton and control systems for small wind, we can offer both the most advanced and the most cost effective instrumentational, control, or telemetry systems.

Modem Options for Communicating with APRS World Products

Digi International makes a wonderful line of 802.15.4 XBee modems. They are fast, powerful, and reliable short range modems. The only downside to the modems is that they aren't readily available, having a lead time of six weeks or more. Faced with a long lead time and a short-deadline project, APRS World designed our own external USB modem that uses a Digi XBee-PRO modem. This product is functionally similar to Digi's XBee-PRO PKG modem package. We also offer an RS-232 potted modem and an Xbee to Ethernet gateway.
