Telesat and SatixFy to demonstrate satellite modems incorporating SatixFy’s Sx3099 1 GHz chip for the Telesat Lightspeed LEO constellation

6-month program initiates early work on the Lightspeed Landing Station and User Terminal modems incorporating the only chip that supports 1 GHz bandwidth and Beam Hopping with hundreds of Mbps IP traffic throughput

Manchester, UK and  Rehovot, Israel – Telesat and SatixFy have signed an agreement giving Telesat early access to SatixFy’s second generation modem chip and will develop prototypes to demonstrate the chip’s capabilities for both Landing Station and User Terminal modems for the Telesat Lightspeed LEO constellation.

The Sx3099 is a second-generation modem chip, simultaneously supporting up to 8 modems in receive and up to 1 GHz of aggregate transmit bandwidth. The Sx3099 processes high speed DVB-RCS2 as well as all modes of the new amended DVB-S2X standard, EN 302 307 v1.4.1, including all new beam hopping superframe formats from format 5 to format 7, as published in 2020. The chip, the first to comply with all new standards requirements, has been tested against the complete set of validation and verification (V&V) reference waveforms published by DVB. SatixFy is a key member of the DVB committee and has made a substantial contribution to the amended standard specification, as well as contributions toward the generation and verification of the reference waveforms included in the V&V package.

SatixFy and Telesat will demonstrate multi-Gbps SCPC gateway links, waveform performance based on internal data path and DSPs, several hundreds of Mbps of data processing capability with the internal quad core ARM A53 CPU, beam hopping waveform performance, synchronization times, throughput and dwell times, and on-chip encapsulation and decapsulation. Several other functions required for Telesat’s Lightspeed constellation will also be demonstrated.

SatixFy will provide Telesat with Sx3099 evaluation boards for performance testing, throughput and data processing capabilities.

SatixFy will also provide multiple Terminal on Modules (ToMs) with dedicated carrier boards for the performance assessment of both Landing Station and User Terminal modems.

As part of the program, SatixFy will deliver initial prototypes of Landing Station modems, based on its ToM carrier boards, for integration with Lightspeed antennas and data processing equipment.

“We are proud to work with Telesat only a few months after our new chip returned from the fab in September 2020. SatixFy was a key contributor to the amended 2020 version of the DVB-S2X standard and is the first to introduce chips that support the new standard following its introduction”, says Yoel Gat, SatixFy’s CEO and founder. “We look forward to delivering a fully functional chip to Telesat that will significantly reduce the schedule, cost and power consumption of the Lightspeed modems.”

“We are eager to validate the highly integrated, high performance Sx3099 modem chip, that will deliver the multiple gigabits per second data processing capability required for our advanced Telesat Lightspeed network,” stated Erwin Hudson, Vice President of LEO for Telesat. “With the ability to support high data rates and with advanced beam hopping features for improved performance and flexibility, the SatixFy modem chip is an ideal modem solution for our next-generation network, allowing us to provide high capacity services for our telecom, enterprise and mobility customers.”

The Sx3099 was developed with support from the UK Space Agency through the European Space Agency’s ARTES Core Competitiveness programme.

Mike Rudd, Head of Telecommunications Strategy at the UK Space Agency said, “The UK Space Agency has been supporting SatixFy in the UK since 2016 through its subscription with ESA – and it’s great to see that our backing is helping to deliver real advancements in technology and collaboration. The agreement between SatixFy and Telesat paves the way for a successful partnership to deliver affordable, quality services through the Telesat Lightspeed network.”

David Peilow, ESA Technical Officer for the project added, “SatixFy developed the state-of-the-art Sx3099 modem chip in less than 18 months under the ESA ARTES programme, incorporating the latest features standardised by DVB and offering performance not previously achieved in mass-market user terminal hardware. The immediate interest of a major operator like Telesat for their Lightspeed network is confirmation that the product brings a step change in capability for satcom. Congratulations to the SatixFy team on this welcome news”.
