L1/L2 receivers are quite a bit more expensive than simple L1 receivers.
An receiver+antenna costs easily 1k€ and more.
On these short baselines you can assume that the same satellite will
see the same ionospheric delay, hence you can compensate for that
when doing common-view with only using L1 data. Or alternatively,
you can work with the IGS data and compensate not only ionospheric
delay but also clock and orbit errors.
