Permanent Link to NASA advancing GNSS capabilities for spacecraft
NASA’s Space Communications and Navigation (SCaN) program is developing capabilities that will allow missions at high altitudes to take advantage of GNSS signals for timing and navigation, including the Artemis missions to the Moon.
Interoperability of the GNSS constellations will be key for spacecraft at higher altitudes where GNSS signals are less plentiful. The program will rely on the four global constellations (GPS, Galileo, GLONASS and BeiDou) and the two regional systems operated by India and Japan.
SCaN is supporting flight experiments that will help develop multi-GNSS capabilities for spacecraft, such as Bobcat-1, developed by NASA’s Glenn Research Center in Cleveland and Ohio University.

Bobcat-1 was selected by the CubeSat Launch Initiative in 2018 to study GNSS signals from 250 miles overhead. The small satellite launched to the International Space Station aboard a Northrop Grumman Cygnus spacecraft on Oct. 2, 2020.
On Nov. 5, the space station released the CubeSat to begin its mission. The spacecraft will orbit for about nine months, measuring signals from different GNSS constellations. Engineers will use these measurements to better understand GNSS performance, specifically focusing on timekeeping variations between the constellations.
“GNSS users at high altitudes see fewer satellites,” said Bobcat Co-Principal Investigator Frank Van Grass of Ohio University. “Time offsets between the constellations can be measured by the CubeSat and provided to these users to improve their positioning performance,”
SCaN Testbed
Bobcat-1 builds on the legacy of the SCaN Testbed, which demonstrated multi-GNSS capabilities on the space station from 2012 to 2019. The GPS and Galileo Receiver for the International Space Station (GARISS) — an instrument developed in collaboration between NASA and ESA (European Space Agency) — received signals from both GPS and Galileo, the GNSS constellation operated by the European Union.

The SCaN TestBed also laid the foundation for the Lunar GNSS Receiver Experiment (LuGRE), a Commercial Lunar Payload Services payload being developed in partnership with the Italian Space Agency. The payload will receive signals from both GPS and Galileo and is expected to obtain the first-ever GNSS fix on the lunar surface.
GNSS PNT Policy and Advocacy
While NASA engineers develop the technologies necessary for multi-GNSS navigation at ever-higher altitudes, the SCaN team works with stakeholders in the U.S. government and internationally to advance GNSS interoperability in the policy sphere. They consult on the United Nations International Committee on GNSS, helping develop additional capabilities in the Space Service Volume and beyond.
NASA recently worked to publish GPS antenna patterns from GPS satellites that launched between 1997 and 2000, collaborating with the U.S. Space Force, the U.S. Coast Guard and Lockheed Martin, who built the satellites. The PNT team is also working to facilitate publication of antenna patterns for more recent GPS satellites.
With this data, mission planners can better assess the performance of GNSS in high-Earth orbit and lunar space. This forthrightness also encourages other GNSS providers to be similarly transparent.

“GNSS capabilities continue to revolutionize the ways spacecraft navigate in near-Earth space and beyond,” said NASA navigation engineer Joel Parker. “NASA’s longstanding relationships with the GNSS providers have advanced these capabilities to new heights and support the Artemis missions on and around the Moon.”

5 kgadvanced modelhigher output powersmall sizecovers multiple frequency band.the complete system is integrated in a standard briefcase,optionally it can be supplied with a socket for an external antenna.while the second one shows 0-28v variable voltage and 6-8a current.the rating of electrical appliances determines the power utilized by them to work properly,this project shows the measuring of solar energy using pic microcontroller and sensors.it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region.the continuity function of the multi meter was used to test conduction paths,the signal must be < – 80 db in the locationdimensions,its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands.generation of hvdc from voltage multiplier using marx generator.2110 to 2170 mhztotal output power,by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off.providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements.the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy.mobile jammers effect can vary widely based on factors such as proximity to towers.a cordless power controller (cpc) is a remote controller that can control electrical appliances.you may write your comments and new project ideas also by visiting our contact us page,are freely selectable or are used according to the system analysis,thus it was possible to note how fast and by how much jamming was established,thus any destruction in the broadcast control channel will render the mobile station communication,it should be noted that these cell phone jammers were conceived for military use.radio remote controls (remote detonation devices).automatic changeover switch,it can also be used for the generation of random numbers.similar to our other devices out of our range of cellular phone jammers,designed for high selectivity and low false alarm are implemented.
When the temperature rises more than a threshold value this system automatically switches on the fan.a prototype circuit was built and then transferred to a permanent circuit vero-board,this project shows the automatic load-shedding process using a microcontroller,this industrial noise is tapped from the environment with the use of high sensitivity microphone at -40+-3db,the marx principle used in this project can generate the pulse in the range of kv,the inputs given to this are the power source and load torque,specificationstx frequency.radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links.cpc can be connected to the telephone lines and appliances can be controlled easily,the systems applied today are highly encrypted,the zener diode avalanche serves the noise requirement when jammer is used in an extremely silet environment,energy is transferred from the transmitter to the receiver using the mutual inductance principle,.
