Do we know 1I is targeted for launch this year too? I mean, its possible considering reports of more failures of atomic clocks in the constellation, but I do not know if there has been any report confirming it so far. 1H is confirmed for the second half of the year to replace 1A.

That's what beidou is saying. This thread is for IRNSS 1I.

Yes. I was referring to the '2nd half of 2017' in the title of the thread. I haven't seen any sources confirming the 1I for launch this year (or I may have missed it) as the original plan was to keep it as a ground spare.

Highly unlikely this will go up in 2017. A H1 2018 launch is more likely i think based on the fact that the construction of this satellite has been outsourced to some private company.

VSSC Director hints at the launch of IRNSS-1I later this year
Quote
The space agency plans to launch an additional space navigation satellite later this year to augment the services of the Rs 1,420 crore NavIC.

"The two spare navigation satellites will make up for any shortfall in the operations and service provided by NavIC to the users round-the-clock over the next 10 years," added Sivan.

There were previous reports of failure of another 3 atomic clocks across the constellation, possibly distributed across multiple satellites as none of the other satellites have been reported to be out of action as yet. IRNSS-1I might be launched to a suitable orbital inclination and location to act as backup for one of these.

Assembly of IRNSS-1I started, targeted for May 2018 as per original plan. No decision yet on building yet another backup
Quote
Is the Assembly of 1I being advanced? Back in December, the consortium of six industries was given six months to work on each spacecraft. The deadline for IRNSS-1I was around May 2018. Dr. Annadurai said that as of now, the timeline was the same. The launch of 1I, when it was ready, would also have to align with ISRO’s other missions, he said.

Payload has likely been shifted to C41 mission
