Read of some research into fitting tiny devices to honey bees to track where they go by a geo ~ stationary satellite.

Can any one out there in wonderful Beekeeping Forum Land help ?

Thanks... and Seasons Greetings !
 
They have to an amateur radio license though before the can have one of these. The bees that is.

Ha ha, geostationary satellite - that would need to be some link budget :)

I guess that Rothamsted.ac have spun their systems down for the Christmas period.
A whois enquiry shows rothamsted.ac as "available". Even Microsoft forgot to renew one of their domains in the 90's. :)
 
Put on a raincoat and a trilby and follow them. They rarely look back, and if they did they'd not recognise you.
 
The Laboratory of Apiculture and Social Insects (LASI) at Sussex University in Brighton have used radio direction finding RDF to monitor the foraging behaviour of workers across the year by attaching tiny transmitters to their thorax's.

They apparently discovered that some colonies can have workers visiting high quality forage up to six miles away from the hive particularly in August when other sources are not available...

Seems unlikely. Geo-stationary satellites are more than 20,000 miles high, anything they receive needs a lot of substantial equipment. A big dish mounted on a van is about as mobile as it usually gets sending signals to them. Satellite geo-location (aka sat-nav) receives from satellites in lower orbit. It's a weak signal and needs some digital processing of the sort found on your dashboard or phone. Even the smallest receivers are a few grams; substantial attached to birds, far too heavy for bees.

There was a talk at the National Honey Show by Margaret Couvillon who was based at LASI. The group used analysis of waggle dances to work out forage sources. Observation hives, lots of video and careful sampling of the direction and duration produced enough samples to show the forage patterns produced over weeks across agricultural crops, gardens and nature reserves.

Electronic tracking that has been documented uses harmonic radar. That's a fairly simple device that bounces back high frequency signals with a frequency shift. No power or processing, so it can be light but the signals are weak and local over a few metres, there's as detailed a description as I've seen here: http://nzes.org.nz/nzje/free_issues/NZJEcol21_2_187.pdf Technology has moved on over a few years but the short distances mean you're confirming what's almost in visual range, not following a full forage range of miles.

If you have any references they could be interesting but probably not involving satellites outside the mapping of results.
