    NASA awards PlanetiQ contract for commercial satellite data acquisition

    NASA has awarded PlanetiQ an expanded contract through its Commercial Smallsat Data Acquisition (CSDA) program, broadening access to commercial satellite data for the scientific community.

    The contract expands PlanetiQ’s CSDA portfolio to add high-SNR GNSS polarimetric radio-occultation data to PlanetiQ’s existing NASA CSDA offerings of ionospheric scintillation, ionospheric total electron content, and high-SNR GNSS radio-occultation data.

    The expanded data offering will provide government researchers with access to advanced GNSS observations that can help improve the understanding of precipitation processes, atmospheric structure, and Earth system dynamics.

    Polarized radio occultation (PRO) measurements have demonstrated the ability to characterize precipitation, detect rain and snowfall structure, identify melting layers, and observe variations in storm intensity. PlanetiQ uses a unique receiver to collect data with a high signal-to-noise ratio (SNR). High-SNR measurements are particularly important for precipitation applications because increased SNR improves sensitivity to lighter precipitation and certain cloud structures.

    “By making polarized radio occultation data available through the CSDA program, NASA is enabling a broader research community to investigate new applications for these observations,” said E. Robert Kursinski, chief scientist, PlanetiQ. “As more researchers gain access to high-SNR PRO data, we expect both the scientific understanding and the potential operational uses of the technology for precipitation and severe weather monitoring to expand.”

    PlanetiQ’s GNSS-PRO measurements are acquired using high-rate, high-SNR receivers that enhance the detection of precipitation signatures and cloud structures. In addition to supporting atmospheric science research, these measurements are critical for operational applications related to rainfall characterization, snowfall detection, storm monitoring, and weather forecasting.

  • PlanetiQ awarded $15M US Air Force contract for GNSS-RO weather data

    PlanetiQ awarded $15M US Air Force contract for GNSS-RO weather data

    PlanetiQ has been awarded a $15 million, 48-month Strategic Funding Increase (STRATFI) contract by the U.S. Air Force. The program will support the development and launch of spacecraft equipped with next-generation GNSS radio occultation (GNSS-RO) and GNSS polarimetric radio occultation (GNSS-PRO) instruments and the delivery of high-value weather data to the U.S. Air Force.

    The mission will focus on advancing GNSS-RO, GNSS-PRO and GNSS reflectometry (GNSS-R) capabilities. The program includes the development of advanced data assimilation techniques to integrate enhanced GNSS-PRO data into numerical weather prediction (NWP) models, improving forecast accuracy and enabling new insights into atmospheric conditions.

    After spacecraft commissioning, PlanetiQ will provide on-orbit data delivery during the contract period. This will support multiple applications across the Department of the Air Force, including artificial intelligence (AI) model training, data assimilation, and performance evaluation.

    As the largest commercial provider of GNSS-RO data, PlanetiQ operates a global constellation of satellites, including spacecraft equipped with advanced receivers capable of capturing high signal-to-noise ratio (SNR) GNSS-RO and GNSS-PRO measurements. GNSS-PRO has demonstrated strong efficacy for measuring precipitation, a key capability for improving severe weather forecasting.

    This STRATFI award will enable the development of a next-generation receiver that adds GNSS-R capabilities, supporting new applications such as ocean surface wind measurement, sea state characterization, and soil moisture monitoring over land.

    “This award represents a major step forward in delivering more advanced, actionable weather information to the warfighter,” said Ira Scharf, CEO of PlanetiQ. “By combining GNSS-RO, PRO and R measurements in a single platform, we are unlocking a more complete picture of the atmosphere and Earth’s surface. We are proud to partner with the U.S. Air Force to accelerate these capabilities and bring next-generation environmental data into operational use.”

  • PlanetiQ wins largest-ever NOAA contract to provide GNSS-RO weather data

    PlanetiQ wins largest-ever NOAA contract to provide GNSS-RO weather data

    PlanetiQ, a provider of commercial weather and space weather data, has been awarded a $24.3 million contract from NOAA’s National Environmental Satellite, Data, and Information Service (NESDIS). The award, issued under the Commercial Data Program’s Radio Occultation Data Buy 2 (RODB-2), is NOAA’s single largest commercial satellite weather data purchase.

    Under the agreement, PlanetiQ will deliver 7,000 GNSS-RO profiles per day, including 500 enhanced high-signal-to-noise ratio (SNR) profiles as well as 2,500 low-latency Total Electron Content (TEC) tracks daily. Data deliveries began Sept. 18.

    “I founded PlanetiQ because radio occultation is one of the few technologies I’ve worked with that tangibly improves the human condition. It’s gratifying to see this capability recognized and scaled.”

    GNSS-RO data from PlanetiQ provides precise vertical profiles of the atmosphere across the globe, over land and sea, and in cloudy and clear conditions. It is recognized as the most impactful satellite data input for weather forecast models. GNSS-RO has become critical to space-based climate monitoring, improving and stabilizing weather prediction and atmospheric research over the past several decades.

    The 500 enhanced high-SNR profiles per day are especially valuable in the lower troposphere, where measurement and forecast accuracy are often most challenging, further enabling actionable decisions and operations planning with reduced risk.

    TEC data additionally strengthens NOAA’s space weather monitoring and forecasting capabilities.

    “This award demonstrates NOAA’s confidence in our ability to deliver both the quantity and quality of data needed to advance weather and space weather forecasting,” said Ira Scharf, chief executive officer of PlanetiQ. “We are proud to expand our support for NOAA and its mission to protect life and property.”

    The new contract represents a threefold increase in PlanetiQ’s data deliveries compared to its most recent NOAA award, which provided 2,200 profiles per day, and is adding the enhanced SNR and TEC tracks as new products. PlanetiQ collects thousands of profiles daily across the planet and plans to expand its constellation of satellites in the future.

    PlanetiQ is excited that organizations running numerical weather prediction, and especially AI forecast models, are recognizing the value in high-quality GNSS-RO data. “Our ability to provide enhanced high-SNR profiles, at seven times the SNR of any other commercial company, sets us apart,” said Chris McCormick, president and chairman of PlanetiQ. “I founded PlanetiQ because radio occultation is one of the few technologies I’ve worked with that tangibly improves the human condition. It’s gratifying to see this capability recognized and scaled.”

    While NOAA is the procuring agency of the GNSS-RO data, it will also be used by NASA, the U.S. Air Force, the U.S. Navy, and international government weather agencies for operational and research purposes.

    This award underscores the critical role of public-private partnerships to bring new capabilities online faster and at a lower cost to strengthen national forecasting and research. PlanetiQ also partners with leading commercial technology companies and data providers.

    The same 91 signers also sent an identical letter to President Biden.

     April 24, 2023 

    Dear Senators and Members of Congress:

    Last year, many of the undersigned wrote in reflection of the unprecedented opposition to the Federal Communications Commission’s (FCC’s) Ligado Order (1) across the vast federal and commercial user base of Global Positioning System (GPS), satellite communications and weather forecasting services. Three years after adoption of the Order, as eight petitions for reconsideration remain pending, (2) we again urge you to work together with the FCC to stay and ultimately set aside the Order. (3) Critically, this is now necessitated by the crucial, previously unavailable information that was produced at the direction of Congress: the independent technical review undertaken by the National Academies of Sciences, Engineering, and Medicine (NAS) (4) analyzing the potential interference issues related to the Ligado Order.

    We greatly appreciate your administration’s opposition to the Ligado Order and commitment that the National Telecommunications and Information Administration (NTIA), on behalf of the executive branch, will continue to actively pursue its petition for reconsideration of the Order. (5) As you know, the pending petitions for reconsideration convincingly demonstrate that the Ligado Order is legally and factually deficient. In the pending petitions, parties showed that the Ligado Order is fundamentally flawed, incompatible with the FCC’s rules and inadequate in protecting incumbent services from the harmful interference from Ligado’s proposed operations. This substantial documentation, among many other concerns from federal and commercial users, resulted in Congress enacting bipartisan legislation in consecutive years after the FCC’s adoption of the Ligado Order, mandating NAS’s independent technical review and requiring the Department of Defense (DoD) to brief federal representatives across the government “at the highest level of classification” on the potential for widespread harm from Ligado’s proposed terrestrial operations. (6) On this basis alone, the FCC should stay the Order in an acknowledgement that it clearly did not account for the full, real-world risk of harm associated with a nationwide terrestrial deployment in the L-band.

    While the pending petitions have a strong likelihood of success on their own merits, the FCC’s rules and the public interest now require the FCC to reconsider the Order in response to the extensive analysis in the NAS Report. (7) This new, previously unavailable information presented in the Congressionally-mandated independent technical review confirms that Ligado’s proposed terrestrial operations would cause harmful interference (8) at significant ranges to incumbent L-band services across a broad range of deployment scenarios. This is consistent with the well-supported and robustly documented analyses and determinations of the federal government, (9) including fourteen federal agencies and departments, (10) and commercial parties (11) alike. Importantly, as concisely stated by DoD and detailed in the NAS Report, “[t]he terrestrial network authorized by [the Ligado Order] will create unacceptable harmful interference for DoD missions. The mitigation techniques and other regulatory provision [sic] in [the Ligado Order] are insufficient to protect national security missions.”(12)

    The unequivocal conclusions of the NAS Report constitute the exact type of previously unavailable information that the FCC’s rules (13) dictate must be addressed on reconsideration. Indeed, NTIA stated on behalf of the executive branch that the NAS Report “offers the [FCC] an important opportunity to reconsider Ligado’s Authorization.”(14) We therefore urge you to work with the FCC to address the harm from Ligado’s proposed terrestrial network to critical GPS, satellite communications, and weather forecasting services by staying the Order, addressing the previously unavailable information contained in the NAS Report, and resolving the pending petitions for reconsideration.

  • GNOMES-3 GNSS radio-occultation satellite launched

    GNOMES-3 GNSS radio-occultation satellite launched

    A new GNSS radio-occultation (RO) satellite is now in orbit. The GNOMES-3 — GNSS Navigation and Occultation Measurement Satellite — flew aboard the SpaceX Falcon 9 Transporter-4 rideshare mission on April 1 and was launched into a 646-km circular sun-synchronous orbit. The payload was powered on and operating nominally within four days of launch.

    The GNOMES-3 was manufactured for PlanetiQ by Blue Canyon Technologies LLC, a wholly owned subsidiary of Raytheon Technologies. Using refracted GNSS signals, PlanetiQ can determine the density and moisture content of the atmosphere to improve weather predictions, helping improve NOAA weather models.

    The GNOMES-3 joins GNOME-2 on orbit and is expected to achieve highly accurate GNSS-RO measurements using the fourth-generation Pyxis-RO sensor. PlanetiQ plans to launch more Pyxis-RO atmospheric and ionospheric sounding spacecraft in 2023. In all, PlanetiQ plans for a fleet of 20 GNOMES by 2024.

    The GNOMES-2, launched in June 2021 on SpaceX’s Transporter-2 mission, produces more than 3,200 soundings of the Earth’s atmosphere and 5,000 ionosphere soundings per day with a large-aperture RO antenna that tracks all four GNSS constellations: GPS, Galileo, GLONASS and BeiDou.

    The soundings have sufficient signal-to-noise ratio to indicate the location of the planetary boundary layer, as well as detect super refraction at the boundary layer and near the Earth’s surface. The higher quality GNSS-RO soundings, along with the associated lower troposphere assimilation tools, will be used to produce more accurate weather forecasting and hurricane tracking, and aid in energy, transportation and agriculture industries as well as serve as a climate record with its SI-traceable data.

  • PlanetiQ signs weather satellite launch contract with India’s Antrix

    PlanetiQ signs weather satellite launch contract with India’s Antrix

    PlanetiQ has signed a contract with Antrix Corporation Limited, the commercial arm of the Indian Space Research Organization (ISRO), for the launch of PlanetiQ’s first two weather satellites on a Polar Satellite Launch Vehicle (PSLV) during the fourth quarter of 2016.

    Ten more satellites are planned for launch in 2017 to complete an initial set of 12 satellites that will dramatically improve global weather forecasting, climate monitoring and space weather prediction, and enable advanced analytics for numerous industries worldwide.

    The ISRO’s PSLV is among the world’s most reliable launch vehicles with 30 consecutive successful flights. It has launched 51 satellites for international customers from 20 countries, in addition to 33 Indian national satellites.

    “The stellar track record of the PSLV combined with our seven-year satellite design life provides the reliability and data continuity not just desired, but required by the operational weather forecast community,” said Chris McCormick, Chairman and CEO of PlanetiQ. “Within days after launch, we will validate and start delivering high-quality data and services to our customers.”

    24 hours of data from 12 PlanetiQ satellites = ~34,000 occultations/day.
    24 hours of data from 12 PlanetiQ satellites = ~34,000 occultations/day.

    Each of PlanetiQ’s 10-kilogram microsatellites will fly PlanetiQ’s Pyxis-RO sensor, an advanced satellite weather sensor in a small package that can penetrate through clouds and storms down to the Earth’s surface. Pyxis-RO uses a technique called radio occultation to track the bending of GPS and other signals as they travel through Earth’s atmosphere, and then converts the bending angle into high-precision measurements of global temperature, pressure and water vapor in the atmosphere, and electron density in the ionosphere.

    Pyxis-RO quadruples the data collection capability of radio occultation sensors on orbit today by tracking signals from all four major satellite navigation systems — GPS, Galileo, Beidou and GLONASS. With 12 satellites on orbit, PlanetiQ will collect 34,000 occultations per day, evenly distributed around the globe with high-density sampling over both land and water.

    Each occultation is a vertical profile of atmospheric data with high vertical resolution, comprised of measurements less than every 200 meters from the Earth’s surface up into the ionosphere. The data is similar to that collected by weather balloons, but more accurate, more frequent and on a global scale.

    “The world today lacks sufficient data to feed into weather models, especially the detailed vertical data that is critical to storm prediction. That’s why we see inaccurate or ambiguous forecasts for storms like Hurricane Joaquin, which can put numerous lives at risk and cost businesses millions of dollars due to inadequate preparation or risk management measures,” McCormick said. “Capturing the detailed vertical structure of the atmosphere from pole to pole, especially over the currently under-sampled oceans, is the missing link to improving forecasts of high-impact weather.”

  • PlanetiQ Selects Blue Canyon to Build Weather Satellites

    PlanetiQ has selected Blue Canyon Technologies to build its weather satellite constellation, set to launch in 2016 and 2017. PlanetiQ chose BCT as a partner in developing the world’s first commercial constellation dedicated to weather, climate and space weather based on BCT’s development track record and its cutting-edge, low-cost design approach that has delivered hundreds of components and systems for numerous space missions, PlanetiQ said.

    PlanetiQ-O“Weather is the next commercial space frontier, as demand grows not only for better forecasts of day-to-day weather, severe storms and hurricanes, but also for weather and climate data solutions that enhance weather readiness, support risk management and increase business intelligence,” said Anne Hale Miglarese, president and CEO of PlanetiQ. “Together, PlanetiQ and BCT bring the innovation, technical expertise and experience to cost-effectively produce the high-quality data needed to transform the weather satellite industry and deliver unprecedented economic value.”

    PlanetiQ has co-located its aerospace engineering team at BCT’s Boulder facilities, where both the satellites and sensors will be manufactured and integrated, and is already working side-by-side with BCT on the initial set of 12 microsatellites. Working together with the PlanetiQ team, BCT has dramatically reduced the satellite size and weight without sacrificing any instrument capabilities.

    “We are certainly pleased to be chosen by PlanetiQ. Weather is emerging as a major growth sector for aerospace, and our partnership with PlanetiQ positions BCT and the state of Colorado to play a leading role,” said George Stafford, president and CEO of BCT. “Our systems and components match well with PlanetiQ’s instrument requirements, and we are glad to be working on this spacecraft and mission.”

    In early June, PlanetiQ announced the successful testing of its first “Pyxis” weather sensor and is setting up for production with BCT. Pyxis collects dense, precise measurements of global temperature, pressure and water vapor — similar to data collected by weather balloons but on a global scale — using a technique called GPS Radio Occultation (GPS-RO). Among the satellite data sources currently ingested into computer weather models, GPS-RO has shown the most cost-effective, highest impact per observation on forecast accuracy. But only a sparse amount of GPS-RO data exists today.

    Pyxis is the only GPS-RO sensor in such a small package that is powerful enough to provide more than 10 times the amount of data available from GPS-RO sensors currently on orbit, and to routinely probe down into the lowest layers of the atmosphere where severe weather occurs.

    “The small size and weight of the Pyxis sensor — combined with BCT’s high-performance mission experience — will allow us to quickly field a constellation to provide the highest quality, most cost-effective weather data ever available,” said PlanetiQ FounderChris McCormick, who leads PlanetiQ’s instrument team and developed the sensors for the only GPS-RO constellation that has provided operational weather forecast data. “With 12 satellites providing 8 million data points per day, GPS-RO will easily become the most important contributor to weather forecast accuracy at a fraction of the cost of traditional weather satellites.”

    PlanetiQ Introduces New 'Pyxis' GPS Sensor
    Figure credit: PlanetiQ

    PlanetiQ has started testing its first Pyxis weather instrument with successful processing of GPS signals. The Pyxis represents a new paradigm in satellite weather sensor technology that can penetrate through clouds and storms to produce the highly calibrated data required to dramatically improve weather forecasting, climate monitoring and space weather prediction, all at a much lower cost than traditional satellite weather instruments, PlanetiQ said.

    Pyxis will track GPS signals traveling through Earth’s atmosphere and convert them into dense, precise measurements of global temperature, pressure and water vapor — similar to data collected by weather balloons but on a global scale — using a technique called GPS radio occultation (GPS-RO).

    Pyxis is the only GPS-RO sensor in such a small package that is powerful enough to routinely probe down into the lowest layers of the atmosphere where severe weather occurs. In addition, Pyxis is able to track signals from all four major satellite navigation systems (GPS, Galileo, Beidou and GLONASS).

    PlanetiQ’s planned microsatellite constellation, with an initial set of 12 satellites launching in 2016 and 2017, will deliver more than 8 million observations per day of temperature, pressure and water vapor, or more than 10 times the amount of data available from GPS-RO sensors currently on orbit.

    GPS-RO has shown the highest impact per observation on forecast accuracy among the satellite data sources ingested into computer weather models, and is particularly effective at improving predictions of high-impact weather such as hurricanes, severe weather outbreaks and winter storms. However, the amount of GPS-RO data available to date has been sparse.

    The Pyxis sensor development team is based in Boulder, Colo., and led by PlanetiQ Founder Chris McCormick, who was instrumental in designing the sensors on the U.S.-Taiwan Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC), the world’s first and only satellite constellation of proven GPS-RO sensors.

    “Weather has an immense human and societal impact and affects businesses on a daily if not hourly basis, with a $9.7 trillion economic influence globally,” said Anne Hale Miglarese, president and CEO of PlanetiQ. “Improving the weather forecast and developing innovative risk analytics tools are critical to mitigate these growing costs, and the key is more high-quality weather data.”

    “The Earth’s atmosphere is radically under-sampled at present especially over the oceans, which cover 70 percent of the Earth’s surface. With the speed of innovation in sensor technology, space hardware and launch, the weather forecast will dramatically change for the better in the near future,” McCormick said. “The Pyxis represents a major step forward in improving forecast accuracy for both routine weather and big storms, while leveraging the latest advances in science, technology and miniaturization to drive down costs.”

    The company PlanetiQ plans to use GNSS to make real-time weather forecasts. PlanetiQ plans to launch a commercial weather satellite constellation by 2017, composed of 12 to 18 small satellites that will capture data as GNSS satellites pass through Earth’s orbital horizon.

    The satellites will use radio occultation to collect data that will supplement computer models on weather, producing more accurate and timely weather forecasts and assessments, PlanetiQ said. The satellites will measure how GPS, GLONASS, and BeiDou radio waves bend as they travel through the atmosphere, a technique that provides snapshots of temperature, pressure and water vapor, as well as insight into whether solar storms are active in the ionosphere, reports Discovery News.
