MeteoTime
MeteoTime was jointly operated by HKW-Elektronik from Wutha-Farnroda , Germany and Meteotest from Bern , Switzerland ; since 2013 it has been a sole subsidiary of HKW-Elektronik.
MeteoTime has been transmitting encrypted meteorological data in Prangins since 2006 via the long-wave transmitter DCF77 (Germany) and until they were set to HBG (Switzerland) in 2011 . For Switzerland, a contract was agreed between the Federal Institute of Metrology and MeteoTime on the basis of an initiative by MeteoTime. As the operator of the HBG, the Federal Institute for Metrology was responsible for broadcasting the weather data supplied by MeteoTime. Since 2011, the signal has only been broadcast on DCF77.
Information on DCF77 and earlier HBG takes 3 minutes. Due to the low transmission capacity of the two transmitters, a data record of only 14 bits per minute can be sent, that is 42 bits per piece of information. It covers the whole of Europe , which has been divided into 90 regions. Each region receives 4 pieces of information per day.
- 22:00 - 03:59 Current day (TODAY in the display)
- 04:00 - 09:59 the following day (DAY 1 in the display)
- 10:00 - 15:59 the following day (DAY 2 in the display)
- 16:00 - 18:59 The following day (DAY 3 in the display)
- 19:00 - 21:59 30 additional regions with a 2-day forecast
The data is likely to be encrypted using a feedback shift register . There are various receivers, primarily digital weather stations (Irox for HBG and DCF77, Oregon for DCF77 etc.) for receiving this data.
