The PolaRx5TR is used to maintain the world's time reference

The University of São Paulo (Universidade de São Paulo), or USP for short, is one of Brazil's top research universities and one of the country's largest.USP offers a wide range of educational and research opportunities in a number of fields, including science, technology, engineering, mathematics, the arts, humanities, and more.USP's emphasis on research and innovation has made it one of Brazil's major technology centre.

In terms of time synchronisation technology, USP has partnered with Septentrio, a leader in global positioning technology, to use Septentrio's PolaRxTR time transfer receivers.
The PolaRxTR is a high-precision time synchronisation device used to send nanosecond-accurate daily data to the Bureau International des Poids et Mesures (BIPM), contributing to the formation of Coordinated Universal Time (UTC). This receiver provides features such as an external atomic clock reference needed to synchronise other caesium clocks, a PPS IN pulse per second to synchronise with UTC, AIM+ anti-jamming technology, and calculation and elimination of local ionospheric errors.

Daniel Varela Magalhães, a professor at USP, mentioned that for more than a decade, USP has been using the PolaRx receiver for time transfer and as a stable and reliable reference station to improve the accuracy of other receivers

Septentrio, headquartered in Leuven, Belgium, is a designer, manufacturer and marketer of high-precision GPS/GNSS receivers for demanding applications requiring accuracy to the decimetre or centimetre level.

PolaRxTR, one of Septentrio's products, is an ultra-precise time synchronisation receiver designed for time and frequency transfer applications, providing reliable synchronisation and full compatibility with the International Advisory Committee on Time and Frequency Recommendation CCTF5 (2015).

The University of São Paulo is not only renowned within Brazil, but is also recognised globally as an important academic institution. It has collaborative relationships with many of the world's leading universities, including with the University of Oxford in the U.K., Nagoya University in Japan, and the University of Hong Kong in China, etc. USP is also actively involved in international research projects and academic activities, such as joining the International University Climate Consortium (IUCC), as well as co-sponsoring the Tropical Universities Consortium (TUCC) with Hainan University, the Chinese Academy of Tropical Agricultural Sciences (CAAS), and other eight key universities and research institutes in tropical regions around the world.

In addition, USP has partnered with the China Agricultural University to establish the Sino-Brazilian Joint College, which aims to cultivate world-class agricultural science, technology and management talents. These collaborative projects are further evidence of USP's influence and leadership in global education and research.
