Multi - Frequency VLBI Observations of NRAO 530
We report on VLBA observations of a γ-ray bright blazar NRAO 530 at multiple frequencies (5, 8, 15, 22, 39, 43, and 45 GHz) in 1997 and 1999. These multi-epoch multi-frequency high-resolution VLBI images exhibit a consistent coredominated morphology with a bending jet to the north of the core. The quasi-simultaneous data observed at five frequencies (5, 8, 15, 22 and 43 GHz) in February 1997 en...
متن کاملFrequency Transfer Using Precise Point Positioning
Using Precise Point Positioning (PPP) we show the potential for comparing frequency standards with time stabilities of under 300 ps in flicker phase noise for time periods of 1 to 10 d. This leads to comparisons at 1 part in 10 or better at 10 d. We compare short baseline PPP results with 2 hour data from the NIST Measurements System. We compare results from the NIST – USNO baseline with hourly...
متن کاملPrecise phase delay estimation in VRAD mission of Kaguya by same beam and multi frequency VLBI methods
Same beam VLBI (very long baseline interferometry) observations of the two sub-satellites of SELENE (KAGUYA) are demonstrated for purpose of the precise gravimetry of the Moon. The same beam VLBI contributes a great deal to cancel out the tropospheric and ionospheric delays and to determine the absolute value of the cycle ambiguity by using the multi frequency VLBI method. As a result, the diff...
متن کاملMulti-frequency & Multi-epoch Vlbi Study of Cygnus A
We present the first multi-frequency phase-referenced observations of Cygnus A done with the VLBA at 15 and 22 GHz. We find a pronounced two-sided jet structure, with a steep spectrum along the jet and a highly inverted spectrum towards the counter-jet. The inverted spectrum and the frequency dependent jet to counter-jet ratio suggest an obscuring torus in front of the counter-jet. From 14 epoc...
متن کاملFast Precise Point Positioning: A System to Provide Corrections for Single and Multi-frequency Navigation
Fast precise point positioning (Fast-PPP) provides Global Navigation Satellite System corrections in real time. Satellite orbits and clock corrections are shown to be accurate to a few centimeters and a few tenths of a nanosecond which, together with the determination of the fractional part of the ambiguities, enable global high-accuracy positioning with undifferenced Integer Ambiguity Resoluti...
