From ISRO 2014 report:

Quote
ASTROSAT is a multi-wavelength astronomy mission aimed at studying the celestial sources and will carry a suite of instruments sensitive over a wide spectral region covering Visible, Ultraviolet, Soft X-ray and Hard X-ray bands. ASTROSAT will be placed in a 650 km near-equatorial orbit using PSLV-XL.

The four X-ray payloads are: Three identical Large Area Xenon-filled Proportional Counters (LAXPC) instrument covering 3-100 keV region, a Cadmium Zinc-Telluride Imager (CZTI) array with coded mask aperture sensitive in 10-100 keV band, a Soft X-ray Imaging Telescope (SXT) using X-ray reflecting mirrors, X-ray CCD for imaging and spectral studies in 0.3 – 8 keV band and a Scanning Sky Monitor (SSM) for detection and monitoring of new and known X-ray sources in 2 – 10 keV region. The UV and Visible bands are covered by an Ultra Violet Imaging Telescope (UVIT) consisting of two identical telescopes, one covering the FUV band (130 – 180 nm) and the second sensitive in NUV (180 – 300 nm) and Visible (350 – 600 nm) bands.

The spacecraft structure is ready. Various subsystems like power package, onboard computer, reaction wheels and various sensors have been integrated to the spacecraft deck and functional checks are completed. Flight Harness installation on equipment panels is also completed.
The integrated SXT payload has undergone the successful completion of all stand alone tests including vibration and thermovac. It has been delivered to the clean room for integration to the spacecraft. The Flight Models (FMs) of all the other payloads are under different stages of testing.

UVIT Payload had been subjected to acceptance level vibration test in all three axes. LAXPC flight detector vibration test was completed successfully and detector is being monitored. Thermovac tests needs to be done. Calibration of each quadrant of CZTI flight detectors with electronics is completed. All three SSM flight Detectors Bench test and Calibration tests at room temperature are completed. They are under stability monitoring before taking up for further testing activities.

ASTROSAT crossed a major milestone – Spacecraft fully assembled and tests initiated

ASTROSAT is the first dedicated Indian astronomy mission aimed at studying distant celestial objects.  The mission is capable of performing observations in Ultraviolet (UV), optical, low and high energy X-ray wavebands at the same time.  The satellite is planned to be launched during the second half of 2015 by PSLV C-34 to a 650 km near equatorial orbit around the Earth. It is significant to note that ASTROSAT is the first mission to be operated as a space observatory by ISRO.

All the payloads and sub-systems are integrated to the satellite.  Mechanical fit checks of the satellite with PSLV payload adaptor were performed successfully. Last week, the spacecraft was fully assembled and switched ON.  Spacecraft parameters are normal, which indicates everything is functioning well. In the coming days, Spacecraft will undergo several environmental tests like Electromagnetic Interference (EMI) – Electromagnetic Compatibility (EMC), Thermal Vacuum, Vibration, Acoustic tests before shipment to Satish Dhawan Space Centre, Sriharikota.

ASTROSAT carries four X-ray payloads, one UV telescope and a charge particle monitor.  Apart from ISRO, four other Indian institutions, viz., Tata Institute of Fundamental Research (TIFR), Indian Institute of Astrophysics (IIA), Inter-University Centre for Astronomy and Astrophysics (IUCAA) and Raman Research Institute (RRI) are involved in payload development.  Two of the payloads are in collaboration with Canadian Space Agency (CSA) and University of Leiscester (UoL), UK.

The RLV-TD mission, the first flight test of an unmanned, scale model of India’s own space shuttle, is second in the list. It will lift off from Sriharikota by the end of July or the beginning of August...

The PSLV C-30 mission will follow with the Astrosat satellite, which is essentially a space-based observatory.

After celebrating 69th Independence Day, ISRO Satellite Centre (ISAC) had yet another eventful day on August 16, 2015, flagging off the nation’s prestigious and ISRO’s sought after satellite ASTROSAT, a mission for deep sky exploration. ASTROSAT was transported to the country’s spaceport at Satish Dawan Space Centre (SDSC), Sriharikota, using a specially designed Satellite Transportation System (STS).

To a query about the launch of satellites made in the US, Kumar said four satellites would be launched with ASTROSAT.

"US satellites will be launched with ASTROSAT. Actually, four of them (satellites). It will go next month," he said.

These four US satellites are likely the four Lemur satellites mentioned above. Not sure, why the Lemurs are listed as UK satellites, has likely something to do with the fact, that Spire has opened a UK office in Glasgow.
