Another tip that helped me back in the day: Take a small ship to the site, with a point defense turret installed. Land as close as possible to the middle of the site. I used a DBX with the PD on the top-front.
When the flying death-bots start attacking, their missiles are the biggest issue. Your ship's PD will take care of most or all of the missiles.
It also helps to "visit" all the pylons without activating them. This will spawn the bots so you can dispatch them early. Once they're gone, activating the pylons will be much faster and easier.
I’d second this. Using a Point Defence, or even better several, can destroy all the sentinels missiles before they hit your SRV and knock it over. Like Fixitman, I use a DBX and fit PD on all the top utility points (one at the front and back, one on each wing,) It may be overkill but I don’t get hit by any missiles anymore.
There‘s a sweet spot a little to the right of the top of the ramp thing where you can land a small ship which I like to park at, it helps a methodical sweep around the site from one side to another as I raise all the pylons and destroy the sentinels that are near them. It also means my ship, and it’s missiles are nice and close when I’m trying to line up to drop the whatnot into the hole and the other sentinels arrive - I got so frustrated on my first trip as I was constantly knocked upside down when trying to park perfectly over the hole.
Two SRVs may help too if ammo/fuel/damage is a potential issue though extra SRVs and Point Defence does diminish the jump range if you’re not going by Carrier. They may help whilst you’re driving around and getting familiar with the general layout and specific locations of sentinels and pylons.
Finally, and apologies for this becoming quite a long post, don’t rush too much when the timers start after charging the first pylon. As you charge each one you get more time and if you avoid crashing and getting stuck you’ll have plenty of time to get around them all and boost jump gently up the ramp to drop the whatnot.
