SMC Signs CRADA to Certify SpaceX Falcon Launcher

The Space and Missile Systems Center (SMC) at Los Angeles Air Force Base, California, has signed a cooperative research and development agreement (CRADA) with Space Exploration Technologies Corp., better known as SpaceX, to certify the company’s Falcon launcher for future National Security Space (NSS) missions.
That could provide the GPS program another alternative to the United Launch Alliance's Delta IV and Atlas V rockets that currently are the only certified launch vehicles capable of lifting NSS payloads into orbit, including GPS spacecraft.

CNAV Tests Begin on GPS L2C and L5 Signals

The U.S. Air Force Space Command (AFSPC ) began testing modernized civil navigation (CNAV) message capabilities on the GPS L2C and L5 signals for the first time yesterday (June 15, 2013).

This first test period is scheduled to continue through July 1 (Julian Day 182), according to a Notice Advisory to NAVSTAR Users (NANU 2013034), although a tentative CNAV test plan shows the tests ending on June 29.

Air Force Proposes Dramatic Redesign for GPS Constellation

[Updated June 3, 2013] With the budget vise tightening, top Pentagon managers are readying some potentially dramatic changes to the GPS constellation — changes that promise to lower both the cost of the satellites and the expense of putting them into orbit.  

The first changes would be subtle and are linked to buying the next block of GPS III satellites — a decision that sources confirm will be made by the end of September.

GNSS Hotspots


State of California, USA
√ The California Agriculture department is using collective intelligence and GPS to “report a pest.” State residents can download the new CDFA smartphone app and use it to photograph and report bad bugs when they see ‘em. Those with iPhones can choose to send GPS coordinates for quick response to invasive pest emergencies.

Di Qiu: Opportunities of Signals

SIDEBAR: Di Qiu's Compass Points

Landing all-weather aircraft safely in storms. Protecting sensitive data not only through encryption but based on the location at which it is being accessed. Ensuring that accurate and timely information reaches first responders responding to emergencies. 

Although still in the early part of her career, Di Qiu has already made significant contributions to these crucial applications of navigation technology.

Calculating Time Offsets

Q: How do you deal with timing differences between GNSSs? 

A: All GNSSs inherently depend on precise timekeeping to measure the satellite/receiver time of flight of signal propagation with sufficient accuracy to compute ranges/distances for multilateration calculations. Each GNSS ground segment therefore dedicates considerable effort to maintaining a highly stable atomic time scale as well as the corresponding offset to global standards such as UTC (Coordinated Universal Time).
