The Economic Times report Dhruva Space, a two-year-old start-up co-founded by space technologist and ham radio operator Sanjay Nekkanti VU3ISS/AB3OE, sealed a deal with AMSAT India on November 30, 2014 to develop HAMSAT II.


HAMSAT I – VO-52 – was a very popular amateur radio satellite

It will be the successor to HAMSAT VO-52 which went silent on July 11, 2014 due to the failure of the on-board lithium ion batteries. HAMSAT provided a valuable communications resource for the amateur radio community for over 9 years.

Dhruva’s satellites are expected to be launched on ISRO’s workhorse Polar Satellite Launch Vehicle (PSLV). Nekkanti said his team is working closely with the space organization for design approvals and testing of the satellite.

The AMSAT India Secretary Nitin Muttin, VU3TYG has released this statement:

We are pleased to announce that AMSAT India and Dhruva Space Pvt. Ltd. have signed a Memorandum of Understanding on November 30th 2014 to pursue the development of a follow up mission to HAMSAT launched in 2005 on-board the PSLV-C6. HAMSAT II is envisioned to fill the gap created by the recent end of life of HAMSAT and shall continue servicing the societal needs in disaster management, amateur/emergency radio communications and education.

Some of the contemplated payloads for HAMSAT II include:
• U/V Analog FM Transponder
• U/V Linear Transponder, 50 kHz
• APRS Digipeater
• Digitalker

COSMOS-2491 RS-46

Dmitry Pashkov R4UAB reports that the COSMOS-2491 satellite carries RS-46 operating on 435.465 MHz and 435.565 MHz (+/- Doppler).

The satellite was launched on December 25, 2013 and is in a 1,515.8 km by 1,489.1 km 82.5 degree inclination orbit.

COSMOS-2499 signals received by Dmitry Pashkov R4UAB

COSMOS-2499 (2014-028E) was launched on May 23, 2014 and is now in a 1,510.6 km by 1,158.8 km 82.4 degree orbit. Dmitry Pashkov R4UAB has received signals from the satellite on approximately 435.465 MHz and 435.565 MHz (+/- Doppler). On November 30 the satellite started identifying itself in Morse code on 435.465 MHz as RS-47.

Launch of Kosmos 2499There has been some mystery concerning the purpose of COSMOS-2499. In a post updated November 20, 2014 Anatoly Zak @RussianSpaceWeb wrote: Ground observations indicated that the mystery satellite had not exceeded 0.3 meters in size. Previously, two Rockot launches with trios of Rodnik/Strela-3M launches also carried Yubileiny (a.k.a. MiR) experimental satellites with a reported mass from 48 to 100 kilograms. As with the previous launch, observers were at a complete loss about the possible purpose of the satellite.

Cosmos-2499 has made a number or orbital changes since it was first launched. For further information see http://www.russianspaceweb.com/Cosmos-2499.html

OSCAR Locator App

OscarLocator-1Tom Doyle W9KE has developed a Windows satellite tracking App that reproduces the graphical display of the original cardboard OSCARLOCATOR .

Most tracking programs use an equirectangular projection which is by far the easiest to program and shows the entire Earth at once. A 3D model is often used which helps visualize orbits but does not show the entire Earth at the same time.

Tom remembers having an easier time visualizing the orbits back in the day (1970’s) when amateurs used cardboard OSCAR Locators with overlays. This Windows program lets you visualize orbits OSCAR Locator style.

SatNOGS Win Hackaday Prize

SatNOGS - Satellite Networked Open Ground Station

SatNOGS – Satellite Networked Open Ground Station

The open-source amateur satellite tracking project SatNOGS has won the Hackaday 1st prize and an amateur radio SDR won 3rd prize.

Six months ago Hackaday challenged their readers to realize the future of open, connected devices, The prize was a ticket to travel into space. The winners were announced at the Electronica trade show in Munich on November 13.

The SatNOGs project is a thrilling example of the benefits of a connected world. It opens up the use of satellite data to a much wider range of humanity by providing plans to build satellite tracking stations, and a protocol and framework to share the satellite data with those that cannot afford, or lack the skills to build their own tracking station. The hardware itself is based on readily available materials, commodity electronics, and just a bit of 3D printing.

William Leijenaar PE1RAH shows how people tracked satellites in the time before PC’s and AMSAT Argentina show how it’s done today.

ARRL OSCAR LocatorIn the 1974 radio amateurs tracked OSCAR 7 (AO-7) using an OSCARLOCATOR that comprised a polar great circle map and overheads for each satellite.

40 years later OSCAR 7 is still operational when in sunlight and thanks to William Leijenaar PE1RAH you can now download the map and overheads to make your very own OSCARLOCATOR. Read his article at

On Thursday, November 6 at 07:35:49 UT a Dnepr rocket carrying the primary payload Asnaro-1 and four microsatellites was launched from Dombarovsky near Yasny. Kosmotras report all spacecraft have been inserted into their target orbits.

The four Japanese microsatellites are:
– ChubuSat-1 (Kinshachi-1) 437.485 MHz CW/AX.25 (Digipeater uplink 145.980 MHz)
– TSUBAME 437.250 MHz CW and 437.505 AX.25
– Hodoyoshi-1 467.674 MHz
– QSAT-EOS (Tsukushi) an AX.25 GMSK payload has been reported but the frequency is unknown.

Signals have been received from both ChubuSat-1 and TSUBAME.

The 50kg class ChubuSat-1 aims to
• Relay messages in amateur service (AX.25 packet radio Digipeater)
• Take pictures of particular site on Earth commanded from the Earth station with an optical camera and an Infra-red camera
• Try to take pictures of space debris commanded from the Earth station with above two cameras
It will have 3 axis stabilisation

Asnaro Mission PatchThe 30kg class TSUBAME aims to
• Demonstrate satellite bus technology for 30kg-class microsatellite and verification of COTS components such as micro-processors, memory and Li-ion batteries in the space environment
• Verify of Control Moment Gyros developed by the Laboratory for Space Systems
• Demonstrate of high-speed attitude manoeuvres technology using Control Moment Gyros. Some sensor data acquisition experiments will be conducted at the same time in order to demonstrate applications of CMGs
• Demonstrate of SRLL communication protocol developed by Tokyo Institute of Technology and high-speed GMSK data downlink
• Collect data through internet with the aid of radio amateurs all over the world
