Small-Satellites, High Altitude Platform Stations (HAPS) and 47 GHz were among the topics discussed at the ITU-D 19th Global Symposium for Regulators in Port Vila, Vanuata, July 9-12.
The background paper ‘Preparing for WRC-19 – Understanding the issues at stake and the impact of decisions to be made’ was among the meeting documents in which 47.0-47.2 GHz is noted as one of the candidate bands for IMT-2020 (International Mobile Telecommunications) and 47.2-47.5 GHz for HAPS.
Regarding Small-Satellites the document says:
At WRC-15, a proposal for a new agenda item for WRC-19 “to consider modifications to the regulatory procedures for notifying satellite networks to accommodate nanosatellite and picosatellite missions” was submitted. WRC-15 decided not to include this as a specific item on the WRC-19 agenda, because it concluded that this matter could best be dealt with by the ITU-R under the standing WRC agenda item 7.
Considering that the size of a satellite is independent of the nature of the service that it is intended to provide, a simplified regulatory regime needs to be developed for non-GSO satellites with short-duration missions, independent of the size of the satellite.
Furthermore, it is important to ensure that any satellite radio-frequency operation avoids harmful interference to incumbent and authorized systems and services. The two frequency bands below 1 GHz under consideration for new or upgraded allocation to the SOS (150.05-174 MHz and 400.15-420 MHz) are used for a wide variety of terrestrial and space applications, including for safety of life purposes, and some of these bands are heavily used on a consistent basis. Nevertheless, if new allocations to the SOS in these frequency bands are considered, they should not put undue constraints on any incumbent services.

The popular ICQ Amateur Radio Podcast has been running for over 11 years and on August 4, 2019, the ICQ Podcast team released their 300th edition which features an interview with Treasurer and Past President of AMSAT Keith Baker KB1SF.
The first edition of ICQ Podcast was released by Father and Son team Martin Butler M1MRB and Colin Butler M6BOY on July 6, 2008 and since those early days the show has gone from strength to strength.
Released fortnightly on a Sunday at 0900 GMT the ICQ Podcast is available either as an MP3 download or as a YouTube version with optional auto-generated subtitles.
In the 300th edition, Martin Butler M1MRB is joined by Chris Howard M0TCH, Dan Romanchik KB6NU and Frank Howell K4FMH to discuss the latest Amateur / Ham Radio news and this episode’s special feature is the interview with AMSAT’s Keith Baker KB1SF which begins at 1:10:30 into the show.

CAMSAT has released details of three new amateur radio satellites, CAS-5A, CAS-5B and CAS-6, that are hoped to launch in September 2018. Two of the satellites CAS-5A and CAS-6 will carry transponders.
CAS-5A a 6U CubeSat which will include the following capabilities:
• HF/HF – H/T Mode Linear Transponder
• HF/UHF – H/U Mode Linear Transponder
• HF – CW Telemetry Beacon
• VHF/UHF – V/U Mode Linear Transponder
• VHF/UHF – V/U Mode FM Transponder
• UHF – CW Telemetry Beacon
• UHF – AX.25 4.8k/9.6k Baud GMSK Telemetry.
The transponders will have 30 kHz bandwidths except the H/U one which will be 15 kHz. Planning a launch in September 2018 from the Jiuquan Satellite Launch Center into a 539×533 km 97.5 degree orbit.
CAS-5B a femto-satellite architecture 90Lx80Wx50H mm with a mass of 0.5kg Proposing a UHF CW beacon and to be deployed from CAS-5A when in space.
CAS-6 a 50 kg micro satellite approx 490 x 499 x 430 mm. It will include:
• VHF CW Telemetry Beacon
• U/V Mode 20 kHz Linear Transponder
• AX.25 4.8k baud GMSK telemetry downlink
• Deployable Antennas
• Solar Panels, Lithium ion battery and power controller
• Integrated Housekeeping Unit
• Three-axis stabilization system
• Atmospheric Wind detector
• S-band TT&C system (non-amateur radio band)
• X-band Data link system (non-amateur radio band)
Planning a Sea Launch Pad from the China Academy of Launch Vehicle Technology in September 2018 into a 579 x 579 km 45 degree orbit.

Emily Calandrelli KD8PKR with her new Ada Lace book
Ada Lace, Take Me to Your Leader is a new book written for young people by Emily Calandrelli KD8PKR that features amateur radio and space communications.
Ada is an 8-year-old with a knack for science, mathematics, and solving mysteries with technology. Her latest project is to fix up a ham radio, something that she could use to contact people on this planet and beyond.
The book is available on Amazon at http://amzn.to/2DbKt9L
