Plans are underway for the CONT 05 campaign on September 12 - 27,
2005. Aside from the traditional VLBI measurements, the other
services ILRS, IGS and IDS have been invited by the IERS and the IVS
to participate. This is an opportunity to collect data and auxilliary
data from each of the space geodetic techniques for combination and
comparison studies. The campaign would include:

1. Continuous VLBI observations during 2 weeks
2. SLR observations on GPS/GLONASS satellites and LEOs with more than
one tracking technique (e.g. CHAMP, JASON-1, GRACE-1&2)
3. DORIS: Best possible tracking at co-location sites with highest
priority on the tracking of multi-technique satellites.
4. GPS: Best tracking at co-location sites, making sure, that the
height differences between GPS, VLBI, WVR, meteo sensor
reference points are known or measured.
5. WVR: As many water vapor radiometers as possible at VLBI sites
6. Meteo: Gather precise meteo info at least at all co-location sites
7. Clocks: Effort to try to run the VLBI and GPS receivers with the
same clock (temperature-stabilized ?) in order to compare the clock
biases and drifts, etc.
8. Gravity measurements: TBD

A coordination group is being formed with representatives from all of
the services:

- IERS : Markus Rothacher
- VLBI : Dirk Behrend + Axel Nothnagel + Arthur Niell
- SLR : Mike Pearlman + Ron Noomen
- DORIS: Pascal Willis + Martine Feissel
- GPS : Gerd Gendt + Angie Moore
- WVR : Arthur Niell

The tasks of the group should be:

1. Inform the individual technique services about the CONT'05
    activities
2. Identify the contributions of the Services to CONT'05
    Campaign
3. Plan and coordinate the activities. etc.

Mike
