Taurus-1 FM to Codec2 Repeater Satellite Launched
BG2BHC reported on Twitter that Taurus-1 launched today on the CZ-4B launch from Taiyuan Satellite Launch Center. Taurus-1 carries an FM to Codec2 repeater that operates using the same protocol as LO-90 (LilacSat-1) and can use the same software (after frequencies are changed). The uplink is 145.840 MHz up and the downlink is 436.760 MHz.
CelesTrak currently has three objects from the launch cataloged out of an expected four. Two objects are in a circular orbit that seem unlikely for a CubeSat given international orbital debris stations (750 km x 730 km). The third cataloged object, Object D is a more likely candidate in a 738 km x 453 km orbit with an inclination of 98.7 degrees. The currently cataloged objects are 2019-059A, 2019-059B, and 2019-059D. TLEs can be found at https://celestrak.com/NORAD/elements/tle-new.txt

Small correction: FM uplink is on 145.820 MHz, downlink on 436.760 MHz, and the telemetry downlink is on 435.840 MHz.

Doppler measurements show that Taurus 1 is object 44530 (2019-059C). Actual telemetry downlink frequency: 435.8387 MHz.
