Migratory animals have innate programs to guide them to their still unknown goal. Highly mobile animals with large ranges develop a so-called navigational ‘map’, a mental representation of the spatial distribution of navigational factors within their home region and their migration route. Readers may recall that the first part was published in November issue. We …

Migratory animals have innate programs to guide them to their still unknown goal. Highly mobile animals with large ranges develop a so-called navigational ‘map’, a mental representation of the spatial distribution of navigational factors within their home region and their migration route. We present here the first part of the paper. The concluding part will …

Since its recovery in 1901 from the seabed near the small Greek island of Antikythera northwest of Crete, a …
The ITU Membership considered and approved a package of three revised ITU-R Recommendations on radionavigation-satellite service (RNSS) systems as listed below.
Recommendation ITU-R M.1787-4 – Description of systems and networks in the radionavigation-satellite service (spaceto- Earth and space-to-space) and technical characteristics of transmitting space stations operating in the bands 1 164-1 215 MHz, 1 215-1 300 …

We have implemented the circuit design comprising of phase detector, limiter, loop filter, NCO and clock divider in hardware using FPGA. The disciplined 10MHz is measured to have a long term (10,000 sec) stability of 1.7 x 10-10. In case of non-availability of NavIC 1PPS, the circuit is designed to work with an internal 1PPS …
