EQUiSat satellite built by students at Brown University in Rhode Island has been launched to the International Space Station
On the small satellite are LED lights. These lights will be so bright that they will be able to seen blinking from Earth while the satellite is passing more than 400 km overhead. They will be as bright as the north star, according to Manav Kohlie, a Brown University student.
Once it is deployed from the Space Station this summer, EQUiSat will use the Earth's magnetic field to orient itself so the LED lights face Rhode Island.
It will transmit a CW beacon and 4FSK 9k6 telemetry on 435.550 MHz.
