Satellite L - Band Systems

GYANDOOT

GYANDOOT is a high performance EDUSAT receiver indigenously designed and developed by Saankhya Labs. GYANDOOT securely delivers digital audio, video, graphics and data content over the EDUSAT network. Powered by Saankhya’s Software defined radio chipset, the low power, compact Satellite IP Receive Only Terminal (RoT), operates on L-Band and interfaces seamlessly to any USB host device such as Laptop or PC. A payload agnostic software utility on the host system enables decryption of encrypted content and utilizes the compute power for software decoding and rendering of multiplexed audio-video and graphics data on the display device. Additionally, GYANDOOT can also receive and store files, e-mails & notification alerts.
