A modern phone contains around 50-70 individual ranging receivers, all capable of operating simultaneously (each with its own spread spectrum sequence, Doppler shift etc).
The GNSS chip typically has 30-60. The 3G modem (if enabled) has ~10 independent receivers (called "fingers" in CDMA parlance). WiFi has 1 (legacy 802.11b).
