Progress on VLBI Ecliptic Plane Survey

Presented by Fengchun SHU on 14 Mar 2016 from 17:00 to 18:00
Type: Poster Presentation
Session: Poster4-6
Track: 5: Geodetic and Astrometric VLBI Results
Board #: S5P8


The goal of VLBI Ecliptic Plane Survey (VEPS) is to increase the number of calibrator radio sources within 7.5 degree of the ecliptic plane by surveying a complete sample of sources with single dish flux densities at 5 GHz greater than 50 mJy. A dense grid of calibrators along ecliptic plane with very accurate coordinates is required for many applications, including observations of spacecrafts in the phase referencing mode. Such observations are used for spacecraft navigation, improvement of planet ephemerides and determination of the Moon’s libration. The VEPS observing program is underway with participation of 3 core Chinese VLBI stations: Seshan25, Kunming and Urumqi, and several international stations that join on ad hoc basis. We will present the current status of the VEPS observing program and show preliminary results.
