The new iMet-4 radiosonde has completed a series of intercomparison flights against the current iMet-1 sonde.  The tests have demonstrated that iMet-1 users can seamlessly upgrade to the new sonde without any data continuity issues.

Commercial production of the iMet-4 will begin in the third quarter of 2017. 

Please contact us for complete test results and methodology. 

InterMet has received 200 first article iMet-4 Radiosondes to continue ground and flight testing.  The iMet-4 is InterMet's newest radiosonde and takes advantages of many developments in sensor and electronic technology since the iMet-1 was introduced in 2006.  More information is available here.

iMet-4 customer shipments will begin during the summer of 2017.   

InterMet is now an authorized value-added distributor of the 3DR Solo UAV.  This follows our development of the hard and software required to interface the iMet-XQ atmospheric sensor with the Solo's on-board processor.  This gives you the ability to stream real-time data from the sensor to your PC while the aircraft is in flight.

InterMet has successfully integrated its iMet-XQ sensor package with the 3DR Solo quadcopter.  The XQ can be connected to the Solo's accessory bay allowing for real-time data to be transferred over the flight control data stream.      

InterMet Is working with 3DR to integrate its UAV sensors into the Solo platform.  The goal is to send real time data over the Solo's communications stream.

Beta testing for the iMet-XQ continues with the release of Version 3.  The product has satisfied the test group as a proof of concept and has been de-bugged and stabilized.  Sensor testing continues, with the next step to be a PCB layout revision to reduce conducted heating of the temperature sensor and possible integration of a new humidity sensor.    

Plesae contact us for more information about testing results so far.

InterMet's Iridium modem has completed flight testing and been formally released as a new product.

The modem sends radiosonde data to the Iridium satelite constellation where it is stored and retransmitted to InterMet's servers.  We then transfer the data to your location.

The modem can transmit for up to 24 hours allowing for new and unusual soundings.  The device was developed for use with high-altitude zero-pressure balloons that will drift for long distances.

iMet-3 RadiosondeThe iMet-3 radiosonde completed it's first successful test flights during the first quarter of 2015 at InterMet Africa's facilities in Cape Town.  

The iMet-3 is InterMet's next-generation radiosonde and is scheduled for commercial production in 2016.


The iMet-XQ UAV sensor package was released in July for beta testing.  Test units have been sent to the Universitiy of Oklohama, the University of Virginia, NOAA's Atmospheric Turbulance and Diffusion Division, the Scottish Marine Institute and the U.S. Naval Postgraduate School.

The iMet-XQ is a self-contained PTU sensor designed for making vertical soundings using rotary-wing UAVs.  For more details, please see:
