With the new receiver we will also start submitting hourly data for KOSG. The last years the future of KOSG, one of the earliest permanent GPS stations serving the IGS (since 1991), has been uncertain following the abandonment and demolition of the Kootwijk Observatory for Satellite Geodesy. After the abandonment of the observatory we have been able, with some difficulty, to continue the GPS observations at KOSG in an unofficial capacity. It is therefore with great pleasure that we can now announce that we have permission by the new owners and local municipality to continue with permanent GPS observations at the site of the former observatory. KOSG will therefore continue to serve the IGS community in future. In the new setup KOSG will have no direct connection to the power grid. The receiver and antenna will be powered using solar panels, hence the new and more power efficient receiver. Data will be transmitted using mobile Internet (currently GPRS, but we are ready for UMTS). The most significant change for KOSG will be that in the next months we will also replace the existing AOAD/M_B DUTD antenna (in operation since 1991) for a more power efficient, Glonass, Galileo and L5 ready, model. Currently we are in the process of selecting a new antenna. The new (and old) antenna will be calibrated absolutely. The antenna change will be announced later. The new and old receiver have been operating in parallel (using a splitter) since 31 July, 2008. Data from both receivers is available from http://gnss1.lr.tudelft.nl/dpga Regards, Hans van der Marel Lennard Huisman -- dr.ir.
