@neotoy I figure you could get a pretty good denial of service on low earth orbit for a budget of less than $5 Million USD.
A soda can's worth of beach sand tossed into orbit with a sling-a-tron style launcher is more than sufficient to start the process.
To get super effective; launch westward; you'll need more delta-vee and a beefier launcher but the differential delta-vee
A couple of dozen sand grains at a differential of more than 20km/s is going to put out enough joules to disable and fragment most of the mini-sats employed by the constellation operators.
