With news of the village finally leaking, we may add some color to other developments. We'll see what time allows today.

For starters, we located the pop-up position of the unit likely previously deployed at Gonggar

As of January 2021, the site at Pagri is nearing completion:

Then there's at least five additional SAM sites north of Arunachal Pradesh at Nariyong, Cona, Longzi, Nyingchi, and Bangda.

Here's the site at Nariyong. It appears this may be an exercise location. (Imagery: @planetlabs)

Next up, the site near Cona, getting closer to completion (Imagery: @planetlabs)

The battery for that position is likely deployed at the old HLZ in town. (Imagery: @planetlabs)

Longzi is also likely complete. Again, hi-cadence medium-resolution imagery from @planetlabs

Then there's the site at Nyingchi. It's co-located at the airport which also recently saw an expanded parking apron, inter alia. (Imagery @planetlabs)

Again, love the time-machine function of @planetlabs imagery showing the Bangda site develop since the Article 370 decision.

In addition to these new sites, we've also seen several compacted earth sites which we're unsure are for deployments or potentially deception. Here's an example from the TAR. (Imagery: @planetlabs)

The site at Bangda also now in Google Earth (h/t @rickrodan)

Speaking of Bangda, there's been considerable effort to begin tunneling into the nearby hillside. Here's an example from the southwest excavation. (I'll leave aside speculation for the moment). Imagery: @planetlabs

Likewise at Gonggar. Excavation was expedited in 2020. Compare December with January. (Imagery: @planetlabs)

This is particularly interesting since they built that second parking apron on the other side of hill.

Other tunneling efforts also appeared at Shigatse near the new SAM site and RTP south of the airfield. Note the three entrances in the @planetlabs imagery. (All improvements were underway in late 2019)

Other tunneling efforts have been identified as well

At the new EW site at Rutog near Pangong Tso. (Imagery: @planetlabs)

In addition, we monitored closely many of the exercise locations in Tibet that were within 250 km of the border. Here's one north of Sikkim where we observed activity since May. (Imagery @planetlabs)

Most had departed by November. (Imagery @planetlabs)

Some of the Chinese road improvement efforts monitored in December 2020. The road runs toward the Sikkim border. (Imagery: @planetlabs)

Here's one of the PLAGF's new posts under construction last month near India's Sikkim border. (Imagery: @planetlabs)

There's also another large post further to the north under construction as well.
