Tethersonde: SmartTether

new tethersonde system tethersonde system in flight

Atmospheric Profiling Solution

SmartTether is Anasphere's tethersonde system. A single low-cost receiver is able to address multiple modules attached to a blimp, kite or tether to gather atmospheric profiles in the lower troposphere. It is orders of magnitude faster and less expensive as compared to traditional tethersonde systems and allows users to collect data simultaneously at multiple points along a tether. SmartTether applications include boundary layer wind profiling, fire weather, pollution monitoring, emergency response and flux measurements.

Features

  • SmartTether has the ability to capture data simultaneously at multiple points (no practical limit) along the tether
  • SmartTether is fast: up to 1Hz data rate
  • SmartTether is inexpensive

Applications

  • Boundary layer wind profiling
  • Fire weather
  • Pollution monitoring
  • Emergency response
  • Flux measurements

SmartTether Basics

The heart of the SmartTether tethersonde is a series of wireless data modules which are attached to the tether. The data rate has been tested at 1 Hz for 6 modules. The data modules send data to a PC-based receiver on the ground. The PC can send commands to an individual data module or an entire network.

The individual modules on the tethersonde are capable of measuring multiple parameters including pressure, temperature, relative humidity, wind speed, and wind direction. The modules have extra analog and digital interfaces for additional sensors allowing the user to customize their system.

The tethersonde can be used to gather flux measurements by making several vertically separated measurements of the species of interest (e.g., carbon dioxide).1

The SmartTether datasheet, manual and software are available on our tethersonde resources page.
