TAHMO

All posts in Weather Stations

TAHMO is seeking a provider of M2M services mainly for African countries.
We are seeking a broad availability of various networks in different countries.

What are we seeking:
– unique M2M sim cards functioning in all or most African countries
– a broad choice of networks as our equipment is located sometimes in remote locations
– we require a maximum of 1Mb of data per month
– we would like a unique price preferable for all Africa or at least per country.
– The price should include a platform accessible by anyone we choose to in order to activate and suspend sim cards.

Documentation to provide when submitting a quote:
– mobile footprint of the available networks your sim cards can access

Please send the offer and documentation to Rebecca Hochreutener by April 28th 2017 12:00 noon CET. Please use” M2M offer ‘name of company’ ”  in the subject of the email. Thank you.


esnc15Prof. Dr Nick van de Giesen, co-director of TAHMO, and Dr. Eugenio Realini won both as special prize winners in the University Challenge and as regional winners for the Netherlands in the 2015 European Satellite Navigation Competition (ESNC). Each year, the ESNC seeks services, products, and business innovations that use satellite navigation in everyday life. The prize pool in ESNC 2015 was valued at approximately 1 million Euros, which included cash awards, business incubation, business coaching, patent consulting, technical support, access to testing facilities, prototype development, publicity, marketing support, and much more. All of the winners were recognized on stage at a festive Awards Ceremony that took place on 20 October in line with the Satellite Masters Conference in Berlin, Germany.

The winning idea: GNSS (global navigation satellite system) monitoring of precipitable water vapour over East Africa using low-cost receivers.

African weather is poorly monitored, especially for forecast purposes. At the same time, African societies are vulnerable to extreme weather events. By far the most critical weather variable is rainfall. To make good predictions about rainfall, it is important to know how much water vapour the atmosphere contains. More water in the atmosphere means more rainfall. Traditionally, this amount of water is measured by weather balloons, but these are expensive and there are only few regular launches over Africa. GNSS signals travel slightly more slowly through moist air than through dry air. A GNSS receiver can measure the extra delay caused by moisture in the atmosphere, even though the differences are very small. Today, even low-cost GNSS receivers are so accurate that they can measure these delays. The plan is to add these low-cost GNSS receivers to the stations of the TAHMO (Trans-African Hydro-Meteorological Observatory) network around Lake Victoria. TAHMO is building a network of 20,000 robust and cost-efficient weather stations across Africa. By adding GNSS/Galileo receivers, it will be possible to greatly improve rainfall predictions.
