The satellite is currently engaged in electrically propelled orbit-raising maneuvers en route to the 28º W.L. orbital location, with arrival anticipated on October 9, 2023.

Currently:

Pretty bad summer for Viasat, hey?

https://www.cnbc.com/2023/08/24/viasats-inmarsat-i6-f2-satellite-suffers-power-failure.html

Anyone know the current orbit for this satellite, or has it not changed since the last update in this thread?

A second Viasat communications satellite is malfunctioning in orbit, this time from the fleet of recently acquired U.K.-based Inmarsat, the company said on Thursday.

The I6 F2 satellite, which Inmarsat launched in February, suffered a failure with its power system while climbing in orbit to where it planned to operate as a backup.

Airbus manufactured the satellite and is, alongside Viasat, assessing whether the satellite can be recovered for use.

A person familiar with the matter told CNBC that the odds of the satellite recovering are low.

Viasat Provides Status of Inmarsat-6 F2

Unexpected anomaly - no material impact to ongoing customer service or recent revenue and Adjusted EBITDA guidance

CARLSBAD, Calif., Aug. 24, 2023 /PRNewswire/ -- Viasat Inc. (NASDAQ: VSAT), a global communications company, today confirmed that its Inmarsat-6 F2 (I6 F2) satellite, which was launched on February 18, 2023, has suffered a power subsystem anomaly during its orbit raising phase. At this stage, Viasat and Airbus, the satellite's manufacturer, are working to determine the root cause of the anomaly and assess whether the satellite will be able to perform its mission. Airbus has advised that this anomaly is an unprecedented event; none of its geostationary telecommunication satellites have ever suffered a failure in orbit.

It is important to note that the I6 F2 anomaly does not impact ongoing customer services, and Viasat does not anticipate that it will materially affect the financial outlook for revenue and Adjusted EBITDA growth discussed in our letter to shareholders dated August 9, 2023. The manufacturing and launch costs of the I6 F2 satellite were insured and near-term cash positions are expected to improve. The twin Inmarat-6 F1 satellite (I6 F1), which was launched in December 2021, is operational and continues to perform as expected.

"I6 F2's initial mission was essentially to provide spare L-band and four Gbps of additional Ka-band capacity, consistent with deploying and operating a resilient, redundant network," said Mark Dankberg, Chairman and CEO, Viasat.

Our satellite fleet assets are key factors in the company's resilience and in enabling sustained growth. The I6 satellites are intended to augment our fleet of geostationary L-band satellites, supplementing capacity and redundant coverage. In addition to our existing L-band fleet, Viasat has a further three L-band satellites (the recently announced Inmarsat-8 satellites) under construction to strengthen the company's global safety services. I6 F2 also included four Gbps of additional Ka-band capacity, which was added to the satellite to provide further flexibility to the legacy Inmarsat Global Xpress (GX) Ka-band fleet. Now, in addition to the 11 existing Ka-band satellites in service for the combined company, and its access to additional partner's satellites, Viasat has seven more Ka-band satellites under construction, which the company anticipates will sustain and enhance its leading and growing global mobility services.

Viasat’s Inmarsat-6 F2 satellite suffers power failure on way to orbital position; total loss feared
written by Peter B. de Selding August 24, 2023

TUPPER LAKE, NY — Viasat's Inmarsat-6 F2 satellite, launched in February, has suffered a power-system failure that may end its useful life and result in a $350 million insurance claim, industry officials said.

The event, which would be the first major satellite failure in London-based Inmarsat’s 40-plus-year history, would also be a rare stain on the reputation of the satellite’s prime contractor, Airbus Defence and Space, which has used its reliability record as a point of sale.

No more signs of life from the satellite.

Viasat Shareholder Letter: Q2 Fiscal Year 2024 Financial Results

Quote
Our satellite manufacturer and antenna supplier have made significant progress in determining the root cause of the ViaSat-3 F1 deployment anomaly. The rest of the spacecraft and payload are performing nominally, or better. Detailed analyses of the antenna status indicate we can obtain sufficient bandwidth, speed and coverage, combined with our existing and planned fleet, and partner space resources, to support our growing global mobility business. Even at less than 10% of its original design capacity, the design of ViaSat-3 F1 allows its available capacity to be allocated flexibly across an expanded coverage area. The anomaly does significantly impact the U.S. residential fixed broadband business, which will remain a smaller portion of current revenue until new capacity can be allocated. Eventually ViaSat-3 F2 or ViaSat-3 F3 will replace ViaSat-3 F1 over the Americas given the opportunities in that market, and the combination of ViaSat-3 F1 with the space assets available in other markets. The ViaSat-3 F3 antennas use a different design from a different supplier. It has a launch contract for the fourth quarter of calendar 2024 (about 1 year away) and is not affected by the anomaly. We expect the ViaSat-3 F1 anomaly investigation will conclude next week and will include recommended corrective actions for ViaSat-3 F2. The details of the corrective actions will drive the launch schedule. We expect to file insurance claims for both ViaSat-3 F1 and Inmarsat-6 F2 before the end of calendar 2023.
