Newbie question - transmitting small packets at near real time speeds

Not possible as stated. The LMIC library waits for the RX1 window to close unconditionally. That's network specific, but at least 1 second, and 5 seconds on The Things Network.

However, if latency is not an issue, you can aggregate location readings, and transmit a large record. At SF7 or SF8, you can transmit 240 bytes. Location fixes are typically 4 bytes of data if you send in binary, so 240 bytes is 60 fixes; if you send every 30 seconds, you'll get the required data density (but there will be latency for the older readings).

Another thing is your device will violate the free band restriction, which is 1% OAT (on air time) for end-nodes.
