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.

VUsat-OSCAR-52_HAMSAT

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 (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.
