CAS-7B Launched and Operational

On July 25, 2019, CAMSAT's CAS-7B satellite was successfully launched on the first orbital launch of iSpace's Hyperbola-1 rocket

CAS-7B is in a very low earth orbit with an apogee of 296 km and a perigee of 278 km The inclination is 42 7 degrees At this altitude, decay is expected by August 11th

CAS-7B carries a 100 mW CW telemetry beacon at 435 715 MHz and an FM transponder with an uplink of 145 900 MHz (16 kHz bandwidth, no tone required) and a downlink of 435 690 MHz (100 mW)

Many QSOs around the world have been reported via the FM transponder Reports indicate the transponder requires a considerable amount of EIRP to access and that the satellite is spinning fast causing rapid fading of signals

More information about CAS-7B can be found at https://www amsat org/camsat-cas-7b-is-ready-for-june-launch/

Upcoming ARISS SSTV Events

ARISS Russia plans to activate the MAI-75 SSTV experiment on July 29 with images starting at 13:15 UTC ending at 21:25 UTC, then again starting July 30 at 13:50 UTC ending 19:30 UTC Downlink frequency is 145 800 MHz FM using the PD-120 SSTV mode

ARISS plans to commemorate Owen Garriott's outstanding accomplishments with ham radio in space during an ISS SSTV event starting 09:40 UTC on August 1 and ending 18:15 UTC on Aug 4 Downlink freq will be 145 800 MHz FM using the PD-120 SSTV mode

However, there is a possible switch out in images for SSTV event scheduled for August 1-4 This may result in planning an additional SSTV event for the end of August that would feature the Owen Garriott commemorative images at that time We expect an update on this after July 26th

AMSAT-Chile developing CESAR-1 FM / digital satellites

AMSAT-CE is designing and building five satellites, to be used by radio amateurs around the world, which will allow a series of scientific experiments in the field of digital communications, as well as gravimetric and orbitgraphic studies

Of these five satellites, one will be the engineering prototype, three will be flight units, and the remaining one will be used to check or replicate on the ground the operation of the units that are in space

AMSAT-CE has also promoted the installation of three earth stations, in Iquique, Temuco and Pto Montt

Technical characteristics

*CESAR-1 is of microsat technonogy (cube shape, 23 cm per edge)

*The satellite reception frequencies will be in the 145 MHz band (5 channels) and 1,575 MHz (GPS)

*The satellite transmission frequencies will be in the 436 MHz band (2 channels)

*The modulation will be FSK (AX 25 9 6 kbps) or narrowband FM

*The magnetic stabilization will be by permanent magnets

*It will have a magnetic brake (the rotation due to the photonic spin will be stopped by seven bars of hydrogen steel, which will cut lines of force from the earth's magnetic field)

*The estimated useful life is 10 years

*The mass will be approximately 12 kg

*The period will be 100 minutes (that's about 14 revolutions a day)

*The satellite platform consists of 5 modules made of space aluminum AL6061-T6

*The electrical energy will be stored in a Saft NiCd battery, made up of 8 batteries of 7 Ah each

*The solar cells will be Spectrolab, triple junction (GalnP2-GaAs-Ge), or the like

Contributions of the CESAR-1 Project to the Country

AMSAT-CE satellites will be added to the projects already undertaken by the Chilean Air Force (FASAT) and the University of Chile (SUCHAI), but they have as their main characteristic that they are the first ones that are being designed and built entirely in the country, which constitutes a huge challenge, and a scientific and technological contribution

Among the benefits that the country and the amateur radio can obtain from AMSAT-CE satellites are:

• Education (interest young people in space radiocommunications)
• Support in emergency situations
• Scientific experimentation (in the frame for experiments)
• Boosting a national aerospace industry
• Experimentation with the Internet
• National Amateur Radio Unit, and
• International recognition for the country

Experiments

The CESAR-1 satellite will have five main (E) experiments:

E1 A digital transponder between two earth stations, to be used in real time, during the period in which both are being illuminated by the satellite (radio-packets in AX 25 at 9,600 kbps)

E2 A digital transponder between two earth stations, to be used in deferred time, as an electronic message box (Store & forward with radio-packets in AX 25 at 9 6 kbps)

E3 An analog repeater that will allow two earth stations that are being illuminated by the satellite to be linked, to broadcast audio (voice) in real time, in FM mode

E4 Communication between two terrestrial repeaters, with link to the satellite, which will allow long distance, but temporary, calls to low-power portable stations (voice, FM, 147 MHz access), and

E5 An on-board GPS receiver, which will collect information for gravimetric and orbitgraphic research

The orbit of CESAR-1 will be low, polar and heliosynchronous (about 800 km high)

*In any case, given the time elapsed, it is possible that both the experiments and the electronic part considered for them must be modernized

Cost of the Project and its Financing

The cost of the project, in money, amounts to about USD 700,000 (necessary for the construction of five satellites, launch of one, implementation of two command and control stations, and three terrestrial repeaters)

Of that amount, around USD 300,000 have already been contributed by external sponsors, and by members of the AMSAT-CE Foundation

However, we have not yet been able to obtain the financing of the remaining USD 400,000

Additionally, and conservatively, we estimate that the project requires some 36,000 man-hours of managers and specialists

Much of those 36,000 hours have already been or are being voluntarily contributed by the AMSAT-CE partners

Essentially, the monetary resources that are still missing are needed to finance the solar cells of CESAR-1, hire professional services to finish the construction of what is pending, and cover the costs of the tests and the first launch

Project status

Although it is a radio amateur project, it does not cease to correspond to a professional and complex project

But the more than 20 years we have been working - without reaching the goal - have exhausted some of our partners, and this has generated a shortage of volunteers

It has not been easy to finish the first satellite - which should have flown in the late 1990s - because in Chile there is still not enough awareness about the possibilities offered by space activity to the country

Despite this, the construction of CESAR-1 is quite advanced (more than 70%):

-5 mechanical satellite structures are built -8 UHF transmitters are finished, and aligned in their working frequencies -The sources of power are finished -The receivers have an advance of 90% -The GPS experiment has an advance of 70% -In the OBC with its EDAC and RAM disk, the software needs to be refined -The international coordination of frequencies in the ITU was concluded, but today it would have to be reactivated, for the time elapsed -There are, yes, the photovoltaic cells, the assembly in Chile and the final tests (which will probably be done in Brazil) -It is also necessary to reactivate the obtaining of the pitcher

Operations are performed from about 5 minutes before the listed AOS to 5 minutes after LOS

Transponder frequencies are 145 900 MHz - 145 930 MHz up and 435 880 MHz - 435 910 MHz down, inverting

The SSTV / digitalker downlink is 437 075 MHz

 The upgrades are necessary to enable students to
continue to talk to astronauts in space via Amateur Radio

 We have reached a great milestone with $33,250 raised
or about 17% towards our goal
 This would not have been
     possible without your outstanding generosity!!
