New DirectTV bird to launch tomorrow from French Guiana
Direct TV which is in the thick of a merger with Echostar is going to see the addition of another satellite to its constellation when an Ariane 4 rocket (Flight 146) launches DirecTV-4S into space (26 November 9:35 pm, French Guiana Time, 27 November morning India time).
A Boeing 601HP satellite, it is the largest of its type built by Boeing Satellite Systems (BSS) and will be the sixth Boeing-made satellite launched this year. In all, it will be the 61st Boeing 601 spacecraft launched to date built by Boeing Space and Communications, the world’s largest satellite manufacturer.
The Ariane 4 rocket that will take the satellite into geostationary orbit at 101 degrees West longitude carries two solid and two liquid strap-on boosters. DirectTV-4S has five antennae, and features highly focused spot beam technology, the first in the DirectTV fleet to have this capability. This technology reuses the same frequencies on multiple spot beams to reach the major television markets where DirecTV delivers the signals of local network affiliates.
The satellite is designed to provide the DirecTV digital satellite television service with more than 300 channels of additional capacity to deliver additional local channels and to strengthen the redundancy of its existing in-orbit fleet of its earlier five satellites.
DirecTV-4S will also be the world’s first commercial satellite to employ high-efficiency solar arrays with triple-junction gallium arsenide solar cells built by Spectrolab a BSS subsidiary. These solar cells are called triple-junction because they employ a three-layered structure, with each layer able to capture and convert a different portion of the solar spectrum.
The DirecTV-4S solar cells will be able to convert 24.5 percent of the sun’s energy into electricity. The spacecraft’s two solar arrays are together designed to deliver 8.3 kilowatts of power at the end of its 15-year design life.
The spacecraft will carry two Ku-band payloads: spot beams for local channels, and a national beam payload. The spot beam payload will use a total of 38 traveling wave-tube amplifiers (TWTAs) ranging in power from 30 to 88 watts. The national beam payload will carry two active transponders with further capability for two active high-power transponders and six active low-power transponders.
Once deployed, the DirecTV-4S solar arrays will stretch to more than 85 feet long from tip to tip, and its antennae will span 24.5 feet in width. The spacecraft fully fueled at launch will weigh 9,400 lbs. (4,260 kg).
The mission is scheduled to lift off during a 38-minute launch window that opens at 9:35 p.m. local time (7:00 am, IST, 4:35 pm PST, 12:35 am GMT, 27 November) from Arianespace’s Guiana Space Center on the northeast coast of South America on 26 November.

Tejas Networks names Arnob Roy as MD and CEO, overhauls top leadership team
The Bengaluru-based telecom gear maker reshuffles its entire top team even as quarterly revenue collapses by 83 per cent
BENGALURU: Tejas Networks is changing the guard at the top, and doing so at speed. The Bengaluru-headquartered telecom equipment maker has elevated Arnob Roy as managing director and chief executive officer, effective April 15, 2026, for a term running through to August 3, 2028, and in the same breath announced new appointments across operations and finance. The timing is pointed: the company is navigating one of the roughest patches in its recent history.
Roy steps up from his role as executive director and chief operating officer, a position he has held since March 2019. He brings more than three decades of experience in the high-technology sector across research and development, operations, and sales. His predecessor, Anand Athreya, resigned last year citing personal reasons and was relieved on June 20, 2025, leaving a gap at the top that has now been formally filled.
The numbers Roy inherits are sobering. Tejas posted a net loss of Rs 211.3 crore in the fourth quarter of fiscal year 2026, a near-194 per cent widening year on year from Rs 71.8 crore in the same period a year earlier. Revenue for the quarter collapsed 82.6 per cent year on year to Rs 333 crore, down from Rs 1,907 crore. EBITDA swung to a loss of Rs 118.2 crore against a profit of Rs 121.5 crore a year ago. The culprit is not hard to identify: Tejas has derived the bulk of its revenue from BSNL’s fourth-generation network project, delivered as part of a Tata Consultancy Services-driven consortium, and that roll-out is now winding down.
Roy, speaking during a post-earnings conference call with analysts, was candid about where the company has been. “The BSNL 4G network went live across 100,000 sites. We deployed our largest indigenous router networks in the country through the BSNL MAN network, as well as in the BharatNet Phase 3 network,” he said, adding that Tejas had also successfully rolled out its 400G and 800G DWDM equipment in domestic and international markets, and continued the deployment of what it describes as the world’s largest satellite IoT network through its vehicle tracking system solution.
The pivot to new revenue streams is already under way. Tejas has partnered with Japan’s Rakuten Symphony and NEC Corporation to push deeper into international markets, with several Open Radio Access Network trials ongoing, one of which concluded recently. The company is also diversifying across equipment categories and geographies to sustain momentum as the BSNL chapter closes.
To prosecute that strategy, Roy needs a full team around him. Preetham Uthaiah has been appointed chief operating officer, moving up from his current role as vice president of product management for wireless products at Tejas Networks. Uthaiah brings nearly 30 years of global experience spanning engineering, product management, and business development across India and the United States. Before joining Tejas Networks, he served as executive vice president of product management, marketing, and strategy at Saankhya Labs, and held senior roles at Tech Mahindra on both sides of the Atlantic. He holds an MBA from Arizona State University and a degree in electronics and communications from Karnatak University.
On the finance front, AVS Prasad has been approved as chief financial officer, effective May 16, 2026, succeeding Sumit Dhingra, who has resigned. Prasad, currently serving as finance controller at Tejas Networks, brings over 27 years of experience within the Tata Group across telecom, aerostructures, and defence. A company secretary and cost and management accountant by training, he has spent more than 15 years in senior finance roles including CFO and financial controller positions, with expertise spanning corporate finance, treasury management, regulatory compliance, internal audit, and governance.
New chief executive, new chief operating officer, new chief financial officer — all installed in a single move, at a moment when the company’s largest revenue source is drying up and the next chapter remains unwritten. Tejas Networks has placed its bets. Now it has to deliver.
