GASV: A New VLBI analysis software for Geodesy and Astrometry
Dang Yao, Yuan-wei Wu, Xu-hai Yang
We present GASV, a novel Python-based software package specifically designed for the analysis of Very Long Baseline Interferometry (VLBI) data. Developed with ease of installation…
Pulsar Timing Observations with Haoping Radio Telescope
Jintao Luo, Yuping Gao, Tinggao Yang +8
We report pulsar timing observations carried out in L-band with NTSC's 40-meter Haoping Radio Telescope (HRT), which was constructed in 2014. The observations were carried out usin…
The NTSC VLBI System and its application in UT1 measurement
Dang Yao, Yuan-Wei Wu, Bo Zhang +8
In order to measure the Universal Time (UT1) in real time, National Time Service Center (NTSC) has built a VGOS-like (VLBI Global Observing System) broadband VLBI network, which in…
A pulsar-based timescale from the International Pulsar Timing Array
G. Hobbs, L. Guo, R. N. Caballero +56
We have constructed a new timescale, TT(IPTA16), based on observations of radio pulsars presented in the first data release from the International Pulsar Timing Array (IPTA). We us…
The application of co-integration theory in ensemble pulsar timescale algorithm
Feng Gao, Ming-Lei Tong, Yu-Ping Gao +2
Employing multiple pulsars and using an appropriate algorithm to establish ensemble pulsar timescale can reduce the influences of various noises on the long-term stability of pulsa…
Optimal Filtration and a Pulsar Time Scale
A. E. Rodin, Ding Chen
An algorithm is proposed for constructing a group (ensemble) pulsar time based on the application of optimal Wiener filters. This algorithm makes it possible to separate the contri…
