The earlier plan apparently was to have the IRNSS-1H (and 1I) built as ground spares by the private Alpha consortium under guidance from ISRO. Is it likely there would be change in those plans now in the aftermath of IRNSS-1A failure?

As per this report, 1H was anyway supposed to be built by March 2017 with ISRO handholding private contractors. So, I guess, they may have already started building it.

From the Annual Report 2016-17

Quote
The space agencies of India and Japan have agreed to further enhance cooperation by signing a new MoU, which enables inclusion of satellite navigation and planetary exploration as additional areas ofcooperation. Both agencies have also agreed to conduct a joint experiment to study Venus atmosphereby collecting signals from JAXA’s Akatsuki mission by ISRO’s ground stations (IDSN). JAXA has agreedto support ISRO to establish a ground station in Japan to support NavIC satellite constellation.

Interview with Nilesh M Desai, Deputy Director, SATCOM & Navigation Applications Area, SAC, ISRO
Quote
Currently, the main challenge is miniaturization. ISRO has already made receivers for both standard and restricted services. We have also shared information such as frequency and other aspects with private vendors and students to work on projects. However, the receiver being used currently is the size of a box. It will reach common people only when it can be embedded in a chip for mobile phone use. We hope that by the year-end, it will have commercial applications.

Within India and 1500 km of its periphery, we have observed up to 5 meters accuracy. Out of around five to six applications today, only Galileo has messaging interface embedded - a feature one will be able to use in NavIC. This feature will be helpful when a command center wants to send warnings to a specific geographic area. For example, fishermen using the system can be warned about a cyclone.
That '5m accuracy' mentioned above must be for the civilian Standard Positioning Service signals.

NAVIC is reportedly operational.

It has both public and military modes.

Reports say regular GPS/GLONASS receivers are not compatible with NAVIC due to different frequency of operation and protocols. ISRO was sponsoring development of public receivers for various types of hardware like mobile devices, civil aircraft, merchant ships etc. but progress is unknown.
