Those are both USB GNSS receivers.  Very few USB GNSS support PPS.  I
have complained to the vendors and they say the PPS confuses users.

The Vk-162 may have a u-blox G6010 or a G7020 in it. u-blox 6-series or
7-series.  You can use ubxtool to reconfigure it.

The Beitab BS-708 is a SiRF BU-353S4.

Neither are very sensitive.  A u-blox 8 or 9 will work better for a similar
price.
