Jamming backups?

The Survey of India complains

South Korea faces the heat.

Where GNSS signals are jammed more than often.

Even US Army would want to limit its dependence on GPS.

The vulnerability of GNSS is increasingly being felt

With increasing dependence on GNSS

Especially on application areas where consequences could be far reaching.

Though endeavors are being made

To make GNSS more robust

Still, the efforts for a few backups,

Must be encouraged

And the ones that existed

Could be revived.
