Without any hint of the PR blitz that I had expected, Intelsat has quietly updated its website to confirm my blog post in March, that it is about to order at least two new satellites, IS-29 and IS-33 to provide high capacity spot beam Ku-band service in the North Atlantic and Indian Ocean regions. These satellites will be in-service in 2015 and 2016 respectively, and are intended to “provide four to five times more capacity per satellite than our traditional fleet” with total throughput “in the range of 25-60 Gbps” (this appears to be a total not a per satellite figure – I would guess the throughput per satellite is around 12Gbps, roughly the same per satellite as Inmarsat’s GX, including its high capacity overlay beams).
UPDATE (June 7): Intelsat has now put out a press release and added more data to its website including a fact sheet, which states specifically that the throughput of 25-60 Gbps is per satellite. Obviously this figure is a wide range but it is clearly much greater than the Global Xpress per satellite capacity. I understand that one reason for Intelsat’s lack of publicity is the quiet period associated with its proposed IPO, but Intelsat definitely considers this a very important development and has been trumpeting it privately to distributors at its recent partner conference.
Intelsat is planning to integrate these new satellites into its existing maritime coverage as shown below (indeed there is less high capacity oceanic coverage than I expected, presumably because it will take time before Intelsat’s existing capacity fills up) and it appears that Intelsat will now be looking to compete head-to-head with Inmarsat’s Global Xpress as well as Viasat (both of which Intelsat appears to be referring to with its comment that “Unlike many new satellite operators, Intelsat is not constrained to Ka-band“)
What we haven’t yet seen are the details of Intelsat’s launch partners. It is clear that one partner is Panasonic, but the more important question is who Intelsat might have managed to secure in the maritime market. Inmarsat’s recent list of XpressLink distribution partners was notable for the absence of Vizada and most other major maritime VSAT providers, so if one or more of these maritime players now makes a substantial commitment to Intelsat, it will be another important sign that the transition to Ka-band in the maritime and aeronautical sectors is far from a foregone conclusion.
