Since the 1960s, geostationary and polar-orbiting environmental satellites have been used by the United States to provide meteorological data for weather observation, research, and forecasting. NOAA’s National Environmental Satellite Data and Information Service (NESDIS) is responsible for managing the civilian geostationary and polar-orbiting satellite systems as two separate programs, called GOES and the Polar Operational Environmental Satellites, respectively. Unlike polar-orbiting satellites, which constantly circle the earth in a relatively low polar orbit, geostationary satellites can maintain a constant view of the earth from a high orbit of about 22,300 miles in space. NOAA operates GOES as a two-satellite system that is primarily focused on the United States (see fig. 1). These satellites are uniquely positioned to provide timely environmental data to meteorologists and their audiences on the earth’s atmosphere, its surface, cloud cover, and the space environment. They also observe the development of hazardous weather, such as hurricanes and severe thunderstorms, and track their movement and intensity to reduce or avoid major losses of property and life. Furthermore, the satellites’ ability to provide broad, continuously updated coverage of atmospheric conditions over land and oceans is important to NOAA’s weather forecasting operations. To provide continuous satellite coverage, NOAA acquires several satellites at a time as part of a series and launches new satellites every few years (see table 1). Three satellites—GOES-11, GOES-12, and GOES-13—are currently in orbit. Both GOES-11 and GOES-12 are operational satellites, while GOES-13 is in an on-orbit storage mode. It is a backup for the other two satellites should they experience any degradation in service. The others in the series, GOES-O and GOES-P, are planned for launch over the next few years. NOAA is also planning a future generation of satellites, known as the GOES-R series, which are planned for launch beginning in 2012. Each of the operational geostationary satellites continuously transmits raw environmental data to NOAA ground stations. The data are processed at these ground stations and transmitted back to the satellite for broadcast to primary weather services both in the United States and around the world, including the global research community. Raw and processed data are also distributed to users via ground stations through other communication channels, such as dedicated private communication lines and the Internet. Figure 2 depicts a generic data relay pattern from the geostationary satellites to the ground stations and commercial terminals. NOAA is planning for the GOES-R program to improve on the technology of prior GOES series, in terms of both system and instrument improvements. The system improvements are expected to fulfill more demanding user requirements and to provide more rapid information updates. Table 2 highlights key system-related improvements GOES-R is expected to make to the geostationary satellite program. The instruments on the GOES-R series are expected to increase the clarity and precision of the observed environmental data. NOAA plans to acquire five different types of instruments. The program office considered two of the instruments—the Advanced Baseline Imager and the Hyperspectral Environmental Suite—to be most critical because they would provide data for key weather products. Table 3 summarizes the originally planned instruments and their expected capabilities. The program management structure for the GOES-R program differs from past GOES programs. Prior to the GOES-R series, NOAA was responsible for program funding, procurement of the ground elements, and on-orbit operation of the satellites, while NASA was responsible for the procurement of the spacecraft, instruments, and launch services. NOAA officials stated that this approach limited the agency’s insight and management involvement in the procurement of major elements of the system. Alternatively, under the GOES-R management structure, NOAA has responsibility for the procurement and operation of the overall system—including spacecraft, instruments, and launch services. NASA is responsible for the procurement of the individual instruments until they are transferred to the overall GOES-R system contractor for completion and integration onto the spacecraft. Additionally, to take advantage of NASA’s acquisition experience and technical expertise, NOAA located the GOES-R program office at NASA’s Goddard Space Flight Center. It also designated key program management positions to be filled with NASA personnel. These positions include the deputy system program director role for advanced instrument and technology infusion, the project manager for the flight portion of the system, and the deputy project manager for the ground and operations portion of the system. NOAA officials explained that they changed the management structure for the GOES-R program in order to streamline oversight and fiduciary responsibilities, but that they still plan to rely on NASA’s expertise in space system acquisitions. Satellite programs are often technically complex and risky undertakings, and as a result, they often experience technical problems, cost overruns, and schedule delays. We and others have reported on a historical pattern of repeated missteps in the procurement of major satellite systems, including the National Polar-orbiting Operational Environmental Satellite System (NPOESS), the GOES I-M series, the Space Based Infrared System High Program (SBIRS-High), and the Advanced Extremely High Frequency Satellite System (AEHF). Table 4 lists key problems experienced with these programs. At the time of our review, NOAA was nearing the end of the preliminary design phase on its GOES-R program and planned to award a contract for the system’s development in August 2007. However, because of concerns with potential cost growth, NOAA’s plans for the GOES-R procurement are changing. To date, NOAA has issued contracts for the preliminary design of the overall GOES-R system to three vendors and expects to award a contract to one of these vendors to develop the system. In addition, to reduce the risks associated with developing new instruments, NASA has issued contracts for the early development of two instruments and for the preliminary designs of three other instruments. The agency plans to award these contracts and then turn them over to the contractor responsible for the overall GOES-R program. However, this approach is under review and NOAA may wait until the instruments are fully developed before turning them over to the system contractor. Table 5 provides a summary of the status of contracts for the GOES-R program. According to program documentation provided to the Office of Management and Budget in 2005, the official life cycle cost estimate for GOES-R was approximately $6.2 billion (see table 6). However, program officials reported that this estimate was over 2 years old and under review. At the time of our review, NOAA was planning to launch the first GOES-R series satellite in September 2012. The development of the schedule for launching the satellites was driven by a requirement that the satellites be available to back up the last remaining GOES satellites (GOES-O and GOES-P) should anything go wrong during the planned launches of these satellites. Table 7 provides a summary of the planned launch schedule for the originally planned GOES-R series. However, NOAA’s plans for the GOES-R procurement are changing because of concerns with potential cost growth. Given its experiences with cost growth on the NPOESS acquisition, NOAA asked program officials to recalculate the total cost of the estimated $6.2 billion GOES-R program. In May 2006, program officials estimated that the life cycle cost could reach $11.4 billion. The agency then requested that the program identify options for reducing the scope of requirements for the satellite series. Program officials reported that there were over 10 viable options under consideration, including options for removing one or more of the planned instruments. The program office also reevaluated its planned acquisition schedule based on the potential program options. Specifically, program officials stated that if there was a decision to make a major change in system requirements, they would likely extend the preliminary design phase, delay the decision to proceed into the development and production phase, and delay the contract award date. At the time of our review, NOAA officials estimated that a decision on the future scope and direction of the program could be made by the end of September 2006. In mid-September 2006, NOAA officials reported that a decision on the future scope and direction of GOES-R had been made—and involved a reduction in the number of satellites and in planned program capabilities, a revised life cycle cost estimate, and the delay of key programmatic milestones. Specifically, NOAA reduced the minimum number of satellites to two. In addition, plans for developing the Hyperspectral Environmental Suite—which was once considered a critical instrument by the agency—were cancelled. Instead, the program office is exploring options that will ensure continuity of sounding data currently provided by the current GOES series. NOAA officials reported that the cost of the restructured program is not known, but some anticipate it will be close to the original program estimate of $6.2 billion. The contract award for the GOES-R system has been pushed out to May 2008. Finally, the planned launch date of the first satellite in the GOES-R series has been delayed until December 2014. NOAA has taken steps to apply lessons learned from problems encountered on other satellite programs to the GOES-R procurement. Key lessons include (1) establishing realistic cost and schedule estimates, (2) ensuring sufficient technical readiness of the system’s components prior to key decisions, (3) providing sufficient management at government and contractor levels, and (4) performing adequate senior executive oversight to ensure mission success. NOAA has established plans designed to mitigate the problems faced in past acquisitions; however, many activities remain to fully address these lessons. Until it completes these activities, NOAA faces an increased risk that the GOES-R program will repeat the increased cost, schedule delays, and performance shortfalls that have plagued past procurements.
