This will be the 7th Proton launch of the year for ILS and the 63rd ILS Proton mission overall since the Proton April 1996 first commercial flight. This will also be the 1st LightSquared satellite launch with Proton. In addition, the SkyTerra 1 will be the 14th Boeing satellite launched on a Proton vehicle.
Spacecraft: MSV-1 (SkyTerra-1)
Platform: Boeing (Hughes) BSS-702
Manufacturer: Boeing
Description and Purpose:
SkyTerra 1 and SkyTerra 2 are the next-generation mobile communications satellite platforms, using both space and terrestrial elements to deliver mobile voice and data services throughout North America
LightSquared (formerly named SkyTerra LP) selected Boeing in January 2006 to build and deliver two Space-Based Networks (SBN), consisting of two 702HP satellites designed for geomobile services, four uplink gateway sites, and Ground-Based Beam Forming (GBBF) equipment. The two SBNs are a component of an integrated satellite-cellular hybrid communications network that will provide ubiquitous fourth-generation coverage throughout the United States and Canada. An SBN will provide user access via typical wireless devices such as cell phones, PDAs, and laptops.
The LightSquared system coverage area comprises the continental United States, Canada, Alaska, Hawaii, Puerto Rico, the Virgin Islands, Mexico and the Caribbean. The SkyTerra SBN system design provides on-orbit flexibility, such as frequency spectrum modification, capacity redistribution and spot beam reconfiguration to meet changing business demands over time. For example, in the event a natural disaster compromises the ground-based cellular service infrastructure, the SBN system can adapt to provide additional voice and data service capacity to the affected geographic region.
The SkyTerra satellites build off the success of the Thuraya mobile communication system. The payloads' utilization of technical advancements (including a larger L-band reflector, digital channelizer and higher power solid state power amplifiers) enables broadband communications through small user terminals that are similar to standard terrestrial devices. The platform incorporates several key new technologies, including an upgraded electrical power subsystem consisting of Lithium-Ion battery packs.
The two satellites are built at Boeing satellite integration and test complex in El Segundo, CA. Harris Corporation of Melbourne, FL. developed the satellites' 22-meter L-band reflector. ViaSat's Comsat Laboratories of Germantown, MD. is providing the GBBF equipment, the uplink beacon stations and the control and monitoring system of the ground stations. SED Systems of Saskatoon, Canada, is providing the antennas, RF elements, and integration services at the gateway stations.
Users of SkyTerra's MSAT devices will have to update their frequencies to adapt for the transition to the new network, as instructed here: http://www.skyterra.com/about/frequency-updates.cfm
A review from the service user's standpoint (http://hothardware.com/News/Can-GSMSatellite-Hybrid-Phones-Go-Mainstream/):
This new hardware will be designed to work with so-called hybrid phones that operate on traditional cell towers (GSM or CDMA, as with current cellphones on AT&T, Verizon, etc.) and satellite service. This capability means that users can safely make calls on normal cell towers while in covered areas, but sat signal can be fetched if users stray too far from the beaten path.
Still, the phones are expected to cost just under $1,000 each, and there's little to no chance that they'll ever end up in retail stores of traditional cellphone operators. On top of all that, sat calls are expected to run customers around $1 per minute, making it outrageously expensive for the average joe. In fact, unless that call was mission critical, we'd wager that the user could either wait until they found a landline or just drive a few miles towards town in order to fetch a single bar of cell signal. Finally, traditional cell service is now much, much more widely available compared to even a decade ago. In fact, it's tough to find too many wide open spaces that can't be reached at least partially by a CDMA or GSM phone. We don't doubt that there's a niche market willing to splurge on a GSM / satellite hybrid phone, but we can't ever see this thing going anywhere close to mainstream.

SkyTerra-1 Ascent Profile
The Proton-M three-stage rocket places the orbital unit (OU), which consists of a Breeze-M upper stage, adapter system and SkyTerra 1, into 51.5° inclination suborbital trajectory. Proton-M powered flight lasts 581 seconds. The OU powered flight begins at the moment of the third stage separation.
Immediately after the separation of the third stage booster, the Breeze-M stability engines start, damping the angular velocities of the third stage separation and then providing orbital unit orientation and stability during coast flight along a suborbital trajectory to await the first burn. The upper stage follows a five-burn injection profile.
