On April 15, TrustPoint, an aerospace startup that provides GNSS products and services, launched its first satellite. The satellite, named It’s About Time, enables TrustPoint to demonstrate core technologies as it progresses towards delivering GPS-independent global time and positioning services.
“TrustPoint’s platform is the first commercially funded, purpose-built PNT microsatellite,” Patrick Shannon, CEO of TrustPoint, said. “With this mission, we are expediting the impact of commercial technologies and innovation cycles on the world of timing and navigation, arguably one of the most far reaching and critical satellite services today.”
Maverick Space Systems, a launch services provider and rideshare aggregator, supported the launch of It’s About Time on SpaceX’s Transporter-7 mission out of Vandenberg Space Force base in California. This first mission focuses on testing, calibration and optimization of TrustPoint’s microsat-compatible GNSS payload technology.
After an initial commissioning period, TrustPoint will take control of the satellite and operate it through a series of tests and demonstrations.
TrustPoint aims for its constellation to deliver secure high precision time and positioning services within the next few years. This capability will help fortify existing critical applications and enable the proliferation of nascent use cases in autonomous navigation, national security and smart infrastructure.
GPS III Space Vehicle 06 (SV06) was launched Jan. 18 from Cape Canaveral Space Force Station in Florida at 7:24 a.m. EST. It is the 18th GPS satellite to broadcast the L5 signal. On Jan. 12, the Space Force Space Systems Command (SSC) had completed encapsulation of SV06 within the Falcon 9 payload.
The launch of SV06 contributed to the SSC’s objective to create resilient GPS, which ensures all users have access to stable positioning, navigation, and timing (PNT) services. SV06, also known as SVN-79, will go through extensive on orbit testing after being introduced into the operational constellation on or about Jan. 25.
Lockheed Martin Space Systems is the main contractor for the GPS III SV06 space vehicle and SpaceX provided launch services. This is Falcon 9’s fifth GPS launch since SpaceX launched GPS III-2 in December 2018.
SV06 is named after the daring pilot Amelia Earhart — the first woman to fly solo across the Atlantic Ocean and to attempt to circumnavigate the world.
The next launch — GPSIII-07 — will take place in 2024.
Constellation Changes. The U.S Space Force Second Space Operations Squadron (2 SOPS) indicates that GPSIII-06, SVN-79/PRN-28, will expand the A2 node in the A plane. It will be identified as position A2F in the vicinity of SVN-52.
SVN-41/PRN-22, forecast unusable until further notice (FCSTUUFN) on Jan. 23, is being set unhealthy and will be used as a test vehicle in AEP.
The scheduled launch of the first GPS III satellite on December 18 was scrubbed, reportedly due to first stage liquid oxygen thermal limit constraints aboard the SpaceX Falcon 9 Block 5 launch vehicle’s first stage reaching safety limits. A second attempt on December 19 was later ruled out due to ongoing evaluations into the sensor issue.
The launch window may open again on Dec. 20.

The first GPS III satellite was originally scheduled to ride aboard a United Launch Alliance (ULA) Delta IV M+ rocket. ULA and/or its prime partners, Lockheed-Martin and Boeing, have conducted every GPS satellite launch since the start of the program. However, due to an assortment of issues variously involving delayed technology development and lawsuits regarding competitive bidding, the Air Force re-opened bidding for the contract as part of its Evolved Expendable Launch Vehicle (EELV) program — “evolved” signifying that the rocket can be recovered and reused.
Recycling Rockets. ULA did not bid on the re-opened contract, citing concerns over the selection process and potential risks with the anticipated lower launch cost. In 2016, the Air Force selected SpaceX to take over most GPS III launches.
SpaceX’s Falcon 9 for this launch will use a new first stage core, the B1054. Although it has re-use capability, it will fly in an expendable configuration this time, with no landing legs and no grid fins. It will be disposed of into the Atlantic Ocean after separation from the second stage.
In other missions, after the satellite-bearing stage separates from the rest of the rocket, the remaining core launcher fires additional fuel to return intact to land or to sea aboard an Autonomous Spaceport Drone Ship (ASDS), a converted barge awaiting in the Atlantic or Pacific Ocean.
New Generation of GPS. As attentive readers already know, GPS III SV01 is the first of an entirely new design of GPS satellite that will help the Air Force modernize today’s GPS constellation with new technology and advanced capabilities.
GPS III has three times better accuracy and up to eight times improved anti-jamming capabilities. Spacecraft life will extend to 15 years, 25 percent longer than any of the GPS satellites on-orbit today. GPS III’s new L1C civil signal also will make it the first GPS satellite broadcasting a compatible signal with other international global navigation satellite systems, like Galileo, improving connectivity for civilian users.
Lockheed Martin developed GPS III and manufactured GPS III SV01 at its GPS III Processing Facility near Denver. In September 2017, the Air Force declared the satellite “Available for Launch” (AFL) and had the company place it into storage. In 2018, the Air Force called up the satellite for launch and Lockheed Martin delivered it to Florida on Aug. 20. The Air Force nicknamed the satellite “Vespucci” after Italian explorer, navigator and cartographer Amerigo Vespucci.
GPS III SV01 is the first of 10 GPS III satellites originally ordered by the Air Force. GPS III SV03-08 are now in various stages of assembly and test. In August, the Air Force declared the second GPS III AFL and in November called GPS III SV02 up for 2019 launch.
The first GPS III satellite has been delivered to Florida for launch in December on a SpaceX rocket.
On Aug. 20, Lockheed Martin shipped GPS III SV01 to Cape Canaveral. GPS III SV01 is the first of 10 new GPS III satellites being built under U.S. Air Force contract and in full production at Lockheed Martin.
Designed and built at Lockheed Martin’s GPS III Processing Facility near Denver, the satellite was transported in a custom container from the Buckley Air Force Base in Colorado to the cape on a massive Air Force C-17 Globemaster III aircraft originating from Joint Base Lewis-McChord, Washington. On Aug. 21, it arrived at the Space Coast Regional Airport in Titusville, Florida.

Start the Clock. The delivery of Satellite Vehicle 01 (SV01) starts the clock for final testing and checkout of the space vehicle prior to launch. The satellite will be processed at the Astrotech Space Operations Florida facility.
A government and contractor team will ensure the integrity of the satellite after shipment by performing a Mission Readiness Test to verify the health and safety of the vehicle, as well as communication compatibility with the ground operations center.
The team will then prepare for propellant loading and encapsulate the satellite in its protective fairing. At the completion of these activities, the satellite will be headed for a first-of-its-kind horizontal integration with the SpaceX Falcon 9 launch vehicle.
GPS III improvements. GPS III will be the most powerful and resilient GPS satellite ever put on orbit. Developed with an entirely new design, for U.S. and allied forces it will have three times greater accuracy and up to eight times improved anti-jamming capabilities over the previous GPS II satellite design block, which makes up today’s GPS constellation.
GPS III also will be the first GPS satellite to broadcast the new L1C civil signal. Shared by other international global navigation satellite systems, like Galileo, the L1C signal will improve future connectivity worldwide for commercial and civilian users.
“The shipment of the first GPS III satellite to the launch processing facility is a hallmark achievement for the program,” said Lt. Gen. John F. Thompson, U.S. Air Force’s Space and Missile Systems Center (SMC) commander and program executive officer for Space. “The modernization of GPS has been an outstanding collaborative effort and this brings us another step closer to launch.”
Vespucci. The satellite is dubbed “Vespucci” in honor of Amerigo Vespucci, the Italian explorer for whom the Americas were named.
The transportation crew consisted of both contractor and government personnel who oversaw the entire operation to ensure that the conditions of the transport environment would not damage any of the satellite’s sensitive components, the Air Force said.
“While the launch of the last GPS IIF satellite marked the end of an era, the upcoming GPS III launch will be the start of a brand new one,” said Col. Steven Whitney, director of the GPS Directorate. “It is the first of our new GPS III satellites, first to integrate with a SpaceX rocket, first to interact with elements of GPS’ Next Generation Operational Control System (OCX) Block 0, and first to have spacecraft acquisition and on-orbit checkout from Lockheed Martin facilities. We are excited to be at this point and we are ready for the upcoming launch of Vespucci.”
December Launch. The modernized GPS III SV01 is slated to launch in December. It will augment the current constellation of 31 operational GPS satellites. GPS delivers the gold standard in positioning, navigation, and timing services supporting vital U.S. and allied operations worldwide, and underpins critical financial, transportation and agricultural infrastructure that billions of users have come to depend on daily.
“Once on orbit, the modern technology of this first GPS III space vehicle will begin playing a major role in the Air Force’s plan to modernize the GPS satellite constellation,” said Johnathon Caldwell, Lockheed Martin’s program manager for navigation systems. “We are excited to start bringing GPS III’s new capabilities to the world and proud to continue to serve as a valued partner for the Air Force’s positioning, navigation and timing mission systems.”
