KM1P Featured in ARRL Letter Article about OMOTENASHI

Boston amateur and AMSAT member Joe Fitzgerald, KM1P, is mentioned in the September 8, 2022 issue of The ARRL Letter. He describes a tool called JPL Horizons, an online solar system data and computation service that provides access to key solar system data for solar system objects such as asteroids, planetary satellites, planets, the Sun, and select spacecraft:

From The ARRL Letter:

When NASA’s Artemis I rocket launches for its mission to the moon this month, you’ll be able to track it using 70-centimeter beacons known as Outstanding MOon exploration TEchnologies demonstrated by NAno Semi-Hard Impactors (OMOTENASHIs).

Omotenashi is Japanese for welcome or hospitality, and it describes the 70-centimeter beacons as small spacecraft and semi-hard landers of the 6U CubeSat format which will demonstrate low-cost technology to land and explore the lunar surface. OMOTENASHI will be one of 10 CubeSats to be carried with the Artemis I mission.

Brian Wilkins, KO4AQF, says that with the Artemis Real-time Orbit Website (AROW), anyone with internet access can pinpoint where Orion is and track its distance from the Earth, its distance from the moon, the mission duration, and more. AROW is available on NASA’s website and Twitter account. AROW visualizes data collected by sensors on Orion that are sent to the Johnson Space Center’s Mission Control Center in Houston during its flight. It will provide periodic real-time data beginning about 1 minute after liftoff through the separation of the Space Launch System (SLS) rocket’s Interim Cryogenic Propulsion Stage, approximately 2 hours into flight.

Once Orion is flying on its own, AROW will provide constant real-time information. On the web, users can follow AROW to see where Orion is in relation to the Earth and the moon, and follow Orion’s path during the mission. Users can view key mission milestones and characteristics on the moon, including information about landing sites from the Apollo program. Also available for download will be an ephemeris, which provides trajectory data from the flight.

AROW will also provide a set of Orion’s state vectors — data that describes precisely where Orion is in space and how it moves — for inclusion in these tweets once Orion is flying on its own. These vectors can be used for data lovers, artists, and creatives to make their own tracking app, data visualization, or anything else they envision. For more information, read https://www.nasa.gov/feature/track-nasa-s-artemis-i-mission-in-real-time/.

AMSAT member Joe Fitzgerald, KM1P, adds a second online tool, called Horizons. The JPL Horizons online solar system data and computation service provides access to key solar system data and flexible production of highly accurate locations for solar system objects such as asteroids, planetary satellites, planets, the Sun, and select spacecraft. Horizons is provided by the Solar System Dynamics Group of the Jet Propulsion Laboratory.

Fitzgerald says to use “OMOTENASHI” as the Target Body. You can find information and the online app at https://ssd.jpl.nasa.gov/horizons.

Newport County Radio Club Experimental Microwave Group Meets

The experimental microwave group of the Newport County (RI) Radio Club (NCRC) gathered to test their AREDN mesh network radios before a site test on Prudence Island in Narragansett Bay.  Two local island women (and club members) recently studied and passed their Technician license specifically to pioneer resilient radio communication on their small island. The NCRC has been experimenting with AREDN (Amateur Radio Emergency Data Network) since 2015, over distances of up to three miles. Today’s gathering was testing the equipment at a local park on 2397 MHz, a super high frequency ham channel below the 2.4GHz WiFi band.

Participants included Paul Fredette, K1YBE; Rob White, KB1ZZU; Mike Cullen, K1NPT; Keith Henry, KC1LPV; and Nancy Austin, KC1NEK. 

Cubes in Space/New England Sci-Tech NASA Balloon Launch, August 16, 2022

Cubes in Space NASA balloon launch pixTo our Cubes in Space Students and Friends of New England Sci-Tech:

NASA Balloon Launch attempt will be TOMORROW morning – Tuesday, 16 August 2022, from NASA’s Columbia Scientific Balloon Facility in New Mexico.

TWO TEAMS of NESciTech students have Cubes-in-Space projects on board to fly.

Video of inflation should begin around 5-5:30 AM EDT (-4GMT).

Launch attempt between 7-9 AM EDT (-4GMT).

NASA says: “Tomorrow we have a VERY small window before monsoonal moisture and winds move in after late morning. Next attempt COULD be Friday if models are correct in predicting a small window of opportunity. It’s going to get rainy and windy in southwest Texas and New Mexico.”

For live location and coordinates: https://towerfts.csbf.nasa.gov/Maps/ConvGPS721NT.htm.

For live stream video: https://video.ibm.com/channel/nasa-csbf-ldsd

Our other two teams’ projects have already flown on the sounding rocket successfully launched from NASA’s Wallops Flight Facility in June. Congratulations to those teams!

Don’t forget – NESciTech students will be doing a “Space Chat” with the astronauts at the BIG E state fair in September. We have room for two more students to join our contact with the International Space Station. Call me ASAP to participate.

Maine Mesh Networking Group Meeting, January 25, 2022

Assistant Director Cory Golob, KU1U, writes:
 
After a Fall hiatus we are going to start resuming the Maine Mesh Network Group meetings.
 
Next Zoom meeting is scheduled for Tuesday, January 25, 2022 at 6:00 PM Eastern. This time worked out the best for most people according to the survey.
 
These meetings are held to discuss expanding MESH networking on 2.4 GHz/5.8 GHz in Maine to benefit the amateur radio community.

ARRL Responds to Story of Radio Amateur Told to Remove His Antenna

From ARRL Web:

09/02/2021 – ARRL has responded to an Orlando, Florida, news story on August 23, 2021 by WFTV Channel 9 alleging a radio amateur was told to remove his antenna by the management of his subdivision following a complaint made by a neighbor.

“The news story appears to stem from a 2-year-old complaint from a neighbor who believed her insulin pump had malfunctioned due to the radio amateur’s operations ‘a few doors down,’” said ARRL Laboratory Manager Ed Hare, W1RFI. “The story is lacking any details or timeline, so I contacted the radio amateur involved for information, and volunteered ARRL’s assistance.”

Hare explained that medical devices such as insulin pumps are regulated by the US Food & Drug Administration (FDA) specifically for electromagnetic compatibility (EMC) purposes and are expected to be capable of operating in all the RF environments likely to be encountered by consumers. FDA published guidance for its staff and industry defines EMC with respect to electrically powered medical devices “as the ability of a device to function safely and effectively in its intended electromagnetic environment, including immunity to electromagnetic disturbance (interference).” FDA review of EMC information submitted with a device for approval “is based on the risk associated with EMC malfunction or degradation of the device under review, as well as the use of appropriate FDA-recognized standards or appropriate consensus standards.”

Hare noted there is an FDA recall for the model number of the insulin pump in question, in approximately the same time frame. “But with so few details, there is no way of knowing whether that recall applies to the serial number used or whether the exact unit has the mechanical defect indicated in the recall notice that could cause the malfunction,” explained Hare.

It also became apparent that there is no actual evidence connecting the amateur’s transmissions to operation of the insulin pump. Hare was told that the amateur agreed to run tests to establish whether there was a cause and effect, but the neighbor declined. 

Hare commented, “While there are no requirements for a radio amateur to stop transmitting due to alleged interference to a non-radio device, the preferred path with any complaint is for neighbors to work together.”
